Hbase shell is taking 63 seconds to scan a table with {LIMIT=>1}! I see
this error occur frequently in the region server logs. Any ideas on
what this might be>
2010-04-20 04:19:41,401 INFO org.apache.hadoop.ipc.HBaseServer: IPC
Server handler 2 on 60020, call next(-750587486574522252) from
10.241.6.80:51850: error:
org.apache.hadoop.hbase.UnknownScannerException: Name:
-750587486574522252
I also see this in the regions server logs:
2010-04-20 04:21:44,559 INFO
org.apache.hadoop.hbase.regionserver.HRegionServer: Scanner
5849633296569445699 lease expired
2010-04-20 04:21:44,560 INFO org.apache.hadoop.hdfs.DFSClient: Could not
obtain block blk_1799401938583830364_69702 from any node:
java.io.IOException: No live nodes contain current block
However "hadoop dfsadmin -report" doesn't show any HDFS issues. Looks
totally healthy. When I do "status" from HBase shell I get
"hbase(main):008:0> status
2 servers, 0 dead, 484.0000 average load" which also seems healthy to
me.
Any suggestions?
