-----------------------------------------
Summary: HBA logs at info level errors that won't show in the shell
Key: HBASE-6916
URL: https://issues.apache.org/jira/browse/HBASE-6916
Project: HBase
Issue Type: Bug
Components: shell
Affects Versions: 0.94.1, 0.92.1, 0.90.6, 0.96.0
Reporter: Jean-Daniel Cryans
Priority: Minor
Fix For: 0.90.7, 0.92.2, 0.94.3, 0.96.0
There is a weird interaction between the shell and HBA. When you try to close a
region that doesn't exist, it doesn't throw any error:
{noformat}
hbase(main):029:0> close_region 'thisisaninvalidregion'
0 row(s) in 0.0580 seconds
{noformat}
Normally one should get UnknownRegionException. Starting the shell with "-d" I
see what a non-shell user would see along with a ton of logging from ZK
(skipped here):
{noformat}
INFO client.HBaseAdmin: No server in .META. for thisisaninvalidregion; pair=null
{noformat}
But again this is not the right message, it should have shown
{noformat}
INFO client.HBaseAdmin: No server in .META. for thisisaninvalidregion; pair=null
{noformat}
And this is because that part of the code treats both UnknownRegionException
and NoServerForRegionException like if it was the same thing.
There is also some ugliness in flush, compact, and split but it normally
doesn't show since the code treats everything like it's a table and sends a
TableNotFoundException.
This jira is about making sure that the exceptions are correctly coming out.
