[jira] Created: (HADOOP-1517) Three methods in FSNamesystem should
not be synchronized.
Three methods in FSNamesystem should not be synchronized.
---------------------------------------------------------
Key: HADOOP-1517
URL: https://issues.apache.org/jira/browse/HADOOP-1517
Project: Hadoop
Issue Type: Bug
Components: dfs
Affects Versions: 0.13.0
Reporter: Konstantin Shvachko
Assignee: Konstantin Shvachko
Priority: Critical
Fix For: 0.14.0
Joining my UTF8 patch HADOOP-1283 with synchronization changes introduced by HADOOP-1269
I missed to remove synchronization modifiers in the following three methods:
startFile()
getAdditionalBlock()
allocateBlock()
Fine grained locking does not work if the first two methods are synchronized.
This is the patch that removes them.
