Totally, there are not many javadoc warnings. We can fix them all in a separate issue. > Prevent region from assigning before log splitting is done > ---------------------------------------------------------- > > Key: HBASE-9514 > URL: https://issues.apache.org/jira/browse/HBASE-9514 > Project: HBase > Issue Type: Bug > Components: Region Assignment > Reporter: Jimmy Xiang > Assignee: Jimmy Xiang > Priority: Blocker > Fix For: 0.96.0 > > Attachments: trunk-9514_v1.patch, trunk-9514_v2.patch, trunk-9514_v3.patch, trunk-9514_v5.1.patch, trunk-9514_v5.1.patch, trunk-9514_v5.2.patch, trunk-9514_v5.3.patch, trunk-9514_v5.4.patch, trunk-9514_v5.5.patch, trunk-9514_v5.patch > > > If a region is assigned before log splitting is done by the server shutdown handler, the edits belonging to this region in the hlogs of the dead server will be lost. > Generally this is not an issue if users don't assign/unassign a region from hbase shell or via hbase admin. These commands are marked for experts only in the hbase shell help too. However, chaos monkey doesn't care. > If we can prevent from assigning such regions in a bad time, it would make things a little safer. -- This message was sent by Atlassian JIRA (v6.1#6144)
