Subject [jira] [Updated] (HBASE-8337) Investigate why disabling hadoop short circuit read is required to make recovery tests pass consistently under hadoop2
Date Tue, 16 Apr 2013 00:18:16 GMT

     [ https://issues.apache.org/jira/browse/HBASE-8337?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jonathan Hsieh updated HBASE-8337:
----------------------------------

    Description: 
HBASE-7636 makes some TestDistributedLogSplitting pass consistently by disabling hdfs short
circuit reads.  
HBASE-8349 makes datanode node death recovery pass consistently by disabling hdfs short circuit
reads.

This will likely require configuration modifications to fix and may have different fixes for
hadoop1, hadoop2 (HDFS-2246), and hadoop3 (HDFS-347)...
