Hi.
I'm trying to create a scanner with custom (Hbase 0.20.3)  filter and it
looks like RegionServer throws an exception:
org.apache.hadoop.hbase.UnknownScannerException: Name: -1

I have my custom filters compiled as a jar and placed in the CLASSPATH in
the RegionServer.
What could be a problem ?

Thank You and Best Regards.

If you search the mailing list, you'll see the same issue came up
recently. Make sure you don't have clients running on 0.20.1

Hi.
Thank You for your reply.
I'm using 0.20.3 on server and client.
I looked in the mailing list and saw couple of messages with the same
problem, but
didn't get any idea how to fix the problem.
My scanner is less than alive 1 minute (less then 10 seconds) , i use 0.20.3
on server and the client.

Thank You and Best Regards.

could you double check your hbase's classpath? we've got the same problem
over here and, in our case, some third-party jars needed by our custom
filter implementation were missing. Maybe this is happening with you too.

You added your filter to HbaseObjectWritable?  (This should no longer
be required when we go to 0.20.4).

Hi.
Sorry, I didn't get you. I just implement Filter interface.
May be I'm doing something wrong with the filter.
Can you please reference me to some sample or guide
how to make a custom filter ?

Thank You and Best Regards.
Slava.

Grep one of the extant filters in the code base.  See where its
mentioned in code.  Do the same with yours.

Hi.
I looked at the Filters code and found that all filter are added to the
static map exactly what you wrote.
It means that I need also add my filter to this map and recompile Hbase ?

Best Regards.

And for sure you restarted both sides of the connection and both sides
are same compiled code?

If so, next up will be seeing whats in the log over on the server.
Mismatched interfaces are ugly to debug.  The messages that come out
don't tell much about whats actually wrong.  If you remove your code,
all works fine?  So its just the addition of your filters that is the
prob?

Hi Slava,

I recently had that problem and the cause was that I wasn't defining a
public default constructor in the filter class. It's required for
deserialization of your filter (the filter is instantiated with the default
constructor and then readFields() is invoked). It's very obscure... scanner
exceptions should be more explicit.

Hi.
Sure i restarted both sides.
The log has ony one exception that I specified - Name: -1.
Scanner on .META and .ROOT are works fine (I put break points on call()
method that
actually calls openScanner() and till my scanner it works fine).

Best Regards.

Hi Sebastien
Thank You for your suggestion, but all my classes Filters and support
classes for the filter are with default ctor.

Thank You and Best Regards.

Is there anything informative in the .out file?  I remember one time I had
an error in a filter's static initializer that caused the class to fail to
load, and it manifested as an uncaught NoClassDefFoundError (
https://issues.apache.org/jira/browse/HBASE-1913 ) showing up there instead
of the .log file.

Hi Dave.
Thank You for your reply, but all .out files (master and region server) are
empty from any exception.

Best Regards.

I have a similar problem, but even with standard filter, when I use it on
the remote client (
http://old.nabble.com/Adding-filter-to-scan-at-remote-client-causes-UnknownScannerException-td27934345.html
).

Haven't solved yet.

Hi to All.
Tried to investigate a bit this problem in the debugger.
It looks like the failure is in connecting region server to open scanner.
And it seems that there problem to connect region server to open scanner (in
any other cases region server is available
for example for put/get operations) , after 10 tries the scanner ID is still
-1 and it passed to the region server  (somehow
in this case connection with region server is succeeded) and server throw an
exception about wrong scanner name.

I have only one region server that is on the same machine where master is
located (single node installation - not a pseudo,
including zookeeper) and also I'm using transactional table (from contrib).

Any idea what could be a problem ?

Best Regards.

Does it work if not transactional in the mix?  That might help narrow
down what is going on here?

Hi.
Open Scanner for .META is working well in the transnational table  (I put
break points in deferent levels , including region server and
ScannerCallable), I don't know if this is indication for something. Tomorrow
I'll try to use regular HTable (requires some work in our infrastructure).
Any way, the exception that is thrown from the ScannerCallable in the case
of no connection to the server after 10 retires should be more informative
and probably the flow of ScannerCallable shouldn't continue to call method
next() in the region server with default value for scanner ID =-1.

I'll let you know tomorrow about my ties using regular HTable.

Thank You and Best Regards.

Hi.
After additional debugging , I found the problem.
During my custom filter serialization (upon Scanner Open operation
Scan.write() ) I tried to serialize variable that is null,
this cause to exception.
Problem is solved.
