[jira] [Commented] (HBASE-5929) HBaseAdmin.compact and flush are
giving confusing errors for ROOT, META, and regions that don't exist
[ https://issues.apache.org/jira/browse/HBASE-5929?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13271054#comment-13271054 ]
Jean-Daniel Cryans commented on HBASE-5929:
-------------------------------------------
I spawed HBASE-5969 for the apparent randomness of the issue with the region that's pre 0.89

> 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 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.
