      Description

      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.
