Andrew Purtell created HBASE-17200: -------------------------------------- Summary: Document an interesting implication of HBASE-15212 Key: HBASE-17200 URL: https://issues.apache.org/jira/browse/HBASE-17200 Project: HBase Issue Type: Bug Components: documentation, Operability, Replication Reporter: Andrew Purtell Priority: Minor
We had a Phoenix client application unfortunately batching up 1000 rows at a time. Phoenix bundles mutations up only considering the row count not byte count (see PHOENIX-541) so this lead to some *single WALEdits* in excess of 600 MB. A cluster without max RPC size enforcement accepted them. (That may be something we should fix - WALEdits that large are crazy.) Then replication workers attempting to ship the monster edits from this cluster to a remote cluster recently upgraded with RPC size enforcement active would see all their RPC attempts rejected, because the default limit is 256 MB. This is an edge case but I can see it happening in practice and taking users by surprise, most likely when replicating between mixed versions. We should document this in the troubleshooting section. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
