[jira] [Created] (ACCUMULO-767) write-ahead logs prematurely
recovered
Eric Newton created ACCUMULO-767:
------------------------------------
Summary: write-ahead logs prematurely recovered
Key: ACCUMULO-767
URL: https://issues.apache.org/jira/browse/ACCUMULO-767
Project: Accumulo
Issue Type: Bug
Components: tserver
Affects Versions: 1.4.0, 1.4.1
Reporter: Eric Newton
Assignee: Keith Turner
Priority: Minor
Fix For: 1.4.2
While using the Distributed Name Node implementation of HDFS (see ACCUMULO-722), a WAL was unnecessarily recovered before it was closed. This happened because a log reference was written to the METADATA table before the location was set. With HDFS, the NameNode recovers the lease and prevents further writes to the log.
