I had the following issues getting it to all work. I don't know if they are known issues so will just list them here first. + I could not find documentation on how to go from tarball to running cluster (the bundled 'cluster' and 'standalone' doc are not about how to get this tarball off the ground). + I had a bit of a struggle putting this release in place under hbase unit tests. The container would just exit w/ 127 errcode. No logs in expected place. Tripped over where minimrcluster was actually writing. Tried to corral it so it played nicely w/o our general test setup but found that the new mini clusters have 'target' hardcoded as output dirs. + Once I figured where the logs were, found that JAVA_HOME was not being exported (don't need this in hadoop-2.0.5 for instance). Adding an exported JAVA_HOME to my running shell which don't seem right but it took care of it (I gave up pretty quick on messing w/ yarn.nodemanager.env-whitelist and yarn.nodemanager.admin-env -- I wasn't getting anywhere) + This did not seem to work for me: <name>hadoop.security.group.mapping</name> <value>org.apache.hadoop.security.JniBasedUnixGroupsMappingWithFallback</value>. It just did this: Caused by: java.lang.UnsatisfiedLinkError: org.apache.hadoop.security.JniBasedUnixGroupsMapping.anchorNative()V at org.apache.hadoop.security.JniBasedUnixGroupsMapping.anchorNative(Native Method) at org.apache.hadoop.security.JniBasedUnixGroupsMapping.<clinit>(JniBasedUnixGroupsMapping.java:49) at org.apache.hadoop.security.JniBasedUnixGroupsMappingWithFallback.<init>(JniBasedUnixGroupsMappingWithFallback.java:38) ..so I replaced it w/ org.apache.hadoop.security.ShellBasedUnixGroupsMapping on the hbase-side to get my cluster up and running. + Untarring the bin dir, it undoes as hadoop-X.Y.Z-beta. Undoing the src dir it undoes as hadoop-X.Y.Z-beta-src. I'd have thought they would undo into the one directory overlaying each other. St.Ack
