Aravind Gottipati created HBASE-5929:
----------------------------------------
Summary: HBaseAdmin.majorCompact and hbase shell randomly throw
exceptions when asked to majorcompact regions.
Key: HBASE-5929
URL: https://issues.apache.org/jira/browse/HBASE-5929
Project: HBase
Issue Type: Bug
Components: client, shell
Affects Versions: 0.92.1
Environment: Linux Ubuntu Lucid 64bit
Reporter: Aravind Gottipati
Priority: Minor
I have been noticing that calls to HBaseAdmin.majorCompact throws exceptions
randomly for some regions. I could not find a pattern to these exception. The
code I have simply does this
admin.majorCompact(region.getRegionNameAsString()). admin is an instance of
HBaseAdmin and region is an instance of HRegionInfo. The exception I get is
org.apache.hadoop.hbase.TableNotFoundException: -ROOT-,,0
at
org.apache.hadoop.hbase.client.HBaseAdmin.tableNameString(HBaseAdmin.java:1473)
~[hbase-0.92.1.jar:0.92.1]
at
org.apache.hadoop.hbase.client.HBaseAdmin.compact(HBaseAdmin.java:1235)
~[hbase-0.92.1.jar:0.92.1]
at
org.apache.hadoop.hbase.client.HBaseAdmin.majorCompact(HBaseAdmin.java:1209)
~[hbase-0.92.1.jar:0.92.1]
at com.stumbleupon.hbaseadmin.HBaseCompact.compactAllServers(Unknown
Source) [hbase_compact.jar:na]
In this case it's the root region, but I get similar exceptions for other
tables, like this.

I see this on hbase shell as well. However, I don't see these exceptions if I
use admin.majorCompact(region.getRegionName()), so it looks like something gets
lost when I use getRegionNameAsString().
Let me know if I can provide more information.
