Hi all,

I've been trying to get HBase (version 0.94.4) working on my system with
Windows 7 for several days now to no avail. I've followed the instructions
at http://hbase.apache.org/cygwin.html and tried to get to the bottom of the
problem myself, but it looks like now I'm stuck. The weird thing is also
that after installing HBase the first time I can use it without problems,
but after stopping HBase and trying to run it again I get the following
error when I try executing commands in the HBase shell:

ERROR: org.apache.hadoop.hbase.MasterNotRunningException: Retried 7 times

I've uploaded the master, regionserver and zookeeper error logs that are
generated as well. I'd appreciate it if someone could spare a few moments
and help me out.

hbase-koen-ncim-master-koen-ncim.log
<http://apache-hbase.679495.n3.nabble.com/file/n4037881/hbase-koen-ncim-master-koen-ncim.log>

<http://apache-hbase.679495.n3.nabble.com/file/n4037881/hbase-koen-ncim-regionserver-koen-ncim.log>

<http://apache-hbase.679495.n3.nabble.com/file/n4037881/hbase-koen-ncim-zookeeper-koen-ncim.log>  

Thanks in advance,

Hi,

>From the logs, it seems you trying to use the non distributed mode:
WARN org.apache.hadoop.hbase.regionserver.HRegionServerCommandLine: Not
starting a distinct region server because hbase.cluster.distributed is false

If it's the case, you don't have to launch a separate zookeeper & region
server. See this: http://hbase.apache.org/book.html#standalone_dist and
this http://hbase.apache.org/book.html#quickstart

May be as well that the previous instance didn't stop properly, or you're
going on a wrong zookeeper:
INFO org.apache.hadoop.hbase.master.ActiveMasterManager: Another master is
the active master, 10.100.0.101,51424,1359964957325; waiting to become the
next active master

So it's worth looking at the processes running on the machine as well.

I've been trying the things suggested under quickstart, but to no avail so
far. One question before getting into more detail: the quickstart section
doesn't mention a hbase-default.xml file in the /conf directory in HBase,
only the hbase-site.xml file. The installation instructions I followed
earlier, however, do involve the hbase-default.xml file.

When trying to get HBase running as a standalone as detailed in the
quickstart section, should the hbase-default.xml file be there (and
configured according to http://hbase.apache.org/cygwin.html) in the /conf
directory of HBase? Or should only the hbase-site.xml file be there,
adjusted according to the quickstart section?

Maybe it's a stupid question, but I'd like to get that cleared up so I have
a better idea of what to do. I've tried running HBase both with and without
the hbase-default.xml configuration file present in /conf after following
the instructions under the quickstart section. Those 2 cases generate
different errors and I'm not sure which case to look at.

In either case, using process explorer to look at the processes yields the
same result. Starting HBase with start-hbase.sh temporarily generates a
bunch of processes, of which 2 bash.exe processes (each with a child
java.exe process) remain. From the process information, one bash process is
a zookeeper instance and the other a master instance. After about a minute
or two, the bash.exe process associated with the master seems to remove/kill
itself. Trying to run commands in the hbase shell then yields the same
MasterNotRunningException.

Well, first you need to decide on what you want to do (i.e; distributed or
not) and acts accordingly.
I would recommend trying with not distributed when you start. This means
you have a single process to launch.

not distributed is the default, so if it can't find the configuration files
it will be not distributed.
When you launch HBase as "not distributed", ZooKeeper and the regions
servers are launched as threads, not processes (I don't have a windows box
to try, but I doubt it's different).

For hbase-default & hbase-site, they are both read when HBase starts,
hbase-site values erase the one from hbase-default if they both exists.
It may be safer to use only hbase-site, and overwrite the values mentionned
in the cygwin page.

I don't understand why you have a separate zookeeper process. Script code
is quite simple for this:

if [ "$distMode" == 'false' ]
then
  "$bin"/hbase-daemon.sh $commandToRun master
else
  "$bin"/hbase-daemons.sh --config "${HBASE_CONF_DIR}" $commandToRun
zookeeper
  "$bin"/hbase-daemon.sh --config "${HBASE_CONF_DIR}" $commandToRun master
  "$bin"/hbase-daemons.sh --config "${HBASE_CONF_DIR}" \
    --hosts "${HBASE_REGIONSERVERS}" $commandToRun regionserver
  "$bin"/hbase-daemons.sh --config "${HBASE_CONF_DIR}" \
    --hosts "${HBASE_BACKUP_MASTERS}" $commandToRun master-backup
fi

So I would recommend to look at this first.

It works now, partially. Starting the master with hbase-daemon.sh, then
starting the hbase shell allows me to succesfully run commands in the hbase
shell now. Although now it gets stuck when I try to disable the test table I
created, but that's a different issue.

As for the seperate Zookeeper process, I don't know how it got there either.
I just followed the instructions on the cygwin page for HBase and doing
start-hbase.sh generates the Zookeeper process after that.
