Eric Newton created HBASE-7878:
----------------------------------
Summary: 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
Reporter: Eric Newton
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.
