Andrew Purtell commented on HBASE-8337:
---------------------------------------
I am no longer getting "foo mentioned you" notices from JIRA.
I don't know why the different users in MiniHBaseCluster. We have this in
init():
{code}
// manually add the regionservers as other users
for (int i=0; i<nRegionNodes; i++) {
Configuration rsConf = HBaseConfiguration.create(conf);
User user = HBaseTestingUtility.getDifferentUser(rsConf,
".hfs."+index++);
hbaseCluster.addRegionServer(rsConf, i, user);
}
{code}
added in r1342856 (HBASE-3194 HBase should run on both secure and vanilla
versions of Hadoop 0.20)
> Investigate why disabling hadoop short circuit read is required to make
> recovery tests pass consistently under hadoop2

> Key: HBASE-8337
> URL: https://issues.apache.org/jira/browse/HBASE-8337
> Project: HBase
> Issue Type: Sub-task
> Components: hadoop2, test
> Affects Versions: 0.98.0, 0.95.1
> Reporter: Jonathan Hsieh
> Priority: Critical
> Fix For: 0.95.1
>
>
> 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)...
