Hudson commented on HBASE-16752: -------------------------------- SUCCESS: Integrated in Jenkins build HBase-1.3-JDK7 #48 (See [https://builds.apache.org/job/HBase-1.3-JDK7/48/]) HBASE-16752 addendum. Do not retry large request for client versions (garyh: rev 3efa3b911294fe0a42440e2aef3865898d91acc0) * (edit) hbase-server/src/main/java/org/apache/hadoop/hbase/ipc/RpcServer.java * (edit) hbase-client/src/main/java/org/apache/hadoop/hbase/exceptions/RequestTooBigException.java > Upgrading from 1.2 to 1.3 can lead to replication failures due to difference > in RPC size limit > ---------------------------------------------------------------------------------------------- > > Key: HBASE-16752 > URL: https://issues.apache.org/jira/browse/HBASE-16752 > Project: HBase > Issue Type: Bug > Components: Replication, rpc > Affects Versions: 2.0.0, 1.3.0 > Reporter: Ashu Pachauri > Assignee: Ashu Pachauri > Fix For: 2.0.0, 1.3.0, 1.4.0 > > Attachments: HBASE-16752.V1.patch, HBASE-16752.V2.patch, > HBASE-16752.addendum.patch > > > In HBase 1.2, we don't limit size of a single RPC but in 1.3 we limit it by > default to 256 MB. This means that during upgrade scenarios (or when source > is 1.2 peer is already on 1.3), it's possible to encounter a situation where > we try to send an rpc with size greater than 256 MB because we never unroll a > WALEdit while sending replication traffic. > RpcServer throws the underlying exception locally, but closes the connection > with returning the underlying error to the client, and client only sees a > "Broken pipe" error. > I am not sure what is the proper fix here (or if one is needed) to make sure > this does not happen, but we should return the underlying exception to the > RpcClient, because without it, it can be difficult to diagnose the problem, > especially for someone new to HBase. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
