Jingcheng Du created HBASE-13855: ------------------------------------ Summary: NPE in PartitionedMobCompactor Key: HBASE-13855 URL: https://issues.apache.org/jira/browse/HBASE-13855 Project: HBase Issue Type: Sub-task Components: mob Affects Versions: hbase-11339 Reporter: Jingcheng Du Assignee: Jingcheng Du Fix For: hbase-11339
In PartitionedMobCompactor, mob files are split into partitions, the compactions of partitions run in parallel. The partitions share the same set of del files. There might be race conditions when open readers of del store files in each partition which can cause NPE. In this patch, we will pre-create the reader for each del store file to avoid this issue. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
