Status: Patch Available (was: Reopened) > [hbase] 'Normal' operation should not depend on throwing of exceptions (e.g. > NotServingRegionException) > ------------------------------------------------------------------------------------------------------- > > Key: HADOOP-1724 > URL: https://issues.apache.org/jira/browse/HADOOP-1724 > Project: Hadoop > Issue Type: Improvement > Components: contrib/hbase > Reporter: stack > Priority: Trivial > > Region server and client logs will have lots of the following when a cluster > is being loaded: > {code} > org.apache.hadoop.hbase.NotServingRegionException: > hbaserepository,,7144829661993961256 > at > org.apache.hadoop.hbase.HRegionServer.getRegion(HRegionServer.java:1208) > at > org.apache.hadoop.hbase.HRegionServer.getRegion(HRegionServer.java:1180) > at > org.apache.hadoop.hbase.HRegionServer.startUpdate(HRegionServer.java:1122) > at > org.apache.hadoop.hbase.HRegionServer.batchUpdate(HRegionServer.java:985) > at sun.reflect.GeneratedMethodAccessor7.invoke(Unknown Source) > at > sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) > at java.lang.reflect.Method.invoke(Method.java:597) > at org.apache.hadoop.ipc.RPC$Server.call(RPC.java:340) > at org.apache.hadoop.ipc.Server$Handler.run(Server.java:566) > {code} > The NotServingRegionException exception is thrown when the remote server is > no longer serving the asked-for region (usually because its been split). The > server throws the exception to provoke the client into making a new > interrogation of region locations. > It would be an improvement if such 'normal' operation was not built atop > exceptions. For example, commits might return a 'region moved' message. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
