Nicolas Liochon commented on HBASE-7878: ---------------------------------------- It's a potential data corruption... On the 'no' side, I'm currently doing some mttr tests, in this seems to be on the critical path now. > recoverFileLease does not check return value of recoverLease > ------------------------------------------------------------ > > Key: HBASE-7878 > URL: https://issues.apache.org/jira/browse/HBASE-7878 > Project: HBase > Issue Type: Bug > Components: util > Affects Versions: 0.95.0, 0.94.6 > Reporter: Eric Newton > Assignee: Ted Yu > Priority: Critical > Fix For: 0.95.0, 0.98.0 > > Attachments: 7878.94, 7878-94.addendum, 7878-94.addendum2, > 7878-addendum.txt, 7878-trunk.addendum, 7878-trunk.addendum2, > 7878-trunk-v10.txt, 7878-trunk-v11-test.txt, 7878-trunk-v12.txt, > 7878-trunk-v13.txt, 7878-trunk-v14.txt, 7878-trunk-v15.patch, > 7878-trunk-v16.txt, 7878-trunk-v2.txt, 7878-trunk-v3.txt, 7878-trunk-v4.txt, > 7878-trunk-v5.txt, 7878-trunk-v6.txt, 7878-trunk-v7.txt, 7878-trunk-v8.txt, > 7878-trunk-v9.txt, 7878-trunk-v9.txt > > > I think this is a problem, so I'm opening a ticket so an HBase person takes a > look. > Apache Accumulo has moved its write-ahead log to HDFS. I modeled the lease > recovery for Accumulo after HBase's lease recovery. During testing, we > experienced data loss. I found it is necessary to wait until recoverLease > returns true to know that the file has been truly closed. In FSHDFSUtils, > the return result of recoverLease is not checked. In the unit tests created > to check lease recovery in HBASE-2645, the return result of recoverLease is > always checked. > I think FSHDFSUtils should be modified to check the return result, and wait > until it returns true. -- This message is automatically generated by JIRA.
