VersionInfoAnnotation Unknown for Hadoop/HBase
Shahab Yunus 2013-04-29, 12:52
Hello,

This might be something very obvious that I am missing but this has been
bugging me and I am unable to find what am I missing?

I have hadoop and hbase installed on Linux machine. Version 2.0.0-cdh4.1.2
and 0.92.1-cdh4.1.2 respectively. They are working and I can invoke hbase
shell and hadoop commands.

When I give the following command:

'hbase version'

I get the following output which is correct and expected:
-----------------------
13/04/29 07:47:42 INFO util.VersionInfo: HBase 0.92.1-cdh4.1.2
13/04/29 07:47:42 INFO util.VersionInfo: Subversion
file:///data/1/jenkins/workspace/generic-package-rhel64-6-0/topdir/BUILD/hbase-0.92.1-cdh4.1.2
-r Unknown
13/04/29 07:47:42 INFO util.VersionInfo: Compiled by jenkins on Thu Nov  1
18:01:09 PDT 2012

But when I I kick of the VersionInfo class manually (I do see that there is
a main method in there), I get an Unknown result? Why is that?
Command:
'java  -cp
/usr/lib/hbase/hbase-0.92.1-cdh4.1.2-security.jar:/usr/lib/hbase/lib/commons-logging-1.1.1.jar
org.apache.hadoop.hbase.util.VersionInfo'

Output:
-----------------------
Apr 29, 2013 7:48:41 a.m. org.apache.hadoop.hbase.util.VersionInfo
logVersion
INFO: HBase Unknown
Apr 29, 2013 7:48:41 a.m. org.apache.hadoop.hbase.util.VersionInfo
logVersion
INFO: Subversion Unknown -r Unknown
Apr 29, 2013 7:48:41 a.m. org.apache.hadoop.hbase.util.VersionInfo
logVersion
INFO: Compiled by Unknown on Unknown

Now this is causing problems when I am trying to run my HBase client on
this machine as the it aborts with the following error:
-----------------------
java.lang.RuntimeException: hbase-default.xml file seems to be for and old
version of HBase (0.92.1-cdh4.1.2), this version is Unknown
   at
org.apache.hadoop.hbase.HBaseConfiguration.checkDefaultsVersion(HBaseConfiguration.java:68)

This means that the hbase-default.xml in the hbase jar is being picked up
but the version info captured/compiled through annotations is not? How is
it possible if 'hbase shell' (or hadoop version') works fine!

Please advise. Thanks a lot. I will be very grateful.

Regards,
Shahab
