Jonathan Hsieh commented on HBASE-4050: --------------------------------------- bq. bq. hbase needs to be recompiled to run against hadoop 2.0 hdfs bq. When did this happen ? In the pom all that changes for the hadoop 2.0 compile are that some dependencies are changed. I just tried on a local machine only and just changing the libs dir I was able to run either version (stand alone only so not really an exhaustive test I know) Here's one reason: https://issues.apache.org/jira/browse/HBASE-5861?focusedCommentId=13259785&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13259785 Here's another: HDFS-1620/HDFS-2412 > Update HBase metrics framework to metrics2 framework > ---------------------------------------------------- > > Key: HBASE-4050 > URL: https://issues.apache.org/jira/browse/HBASE-4050 > Project: HBase > Issue Type: New Feature > Components: metrics > Affects Versions: 0.90.4 > Environment: Java 6 > Reporter: Eric Yang > Assignee: Alex Baranau > Priority: Critical > Fix For: 0.96.0 > > Attachments: 4050-metrics-v2.patch, 4050-metrics-v3.patch, > HBASE-4050.patch > > > Metrics Framework has been marked deprecated in Hadoop 0.20.203+ and 0.22+, > and it might get removed in future Hadoop release.
