HBase trunk on 0.23 Was: Update on hadoop-0.23
Ted Yu 2011-09-29, 01:56
Minor correction to Todd's report, currently HBase TRUNK doesn't compile
against 0.23 (
https://builds.apache.org/view/G-L/view/HBase/job/HBase-TRUNK-on-Hadoop-23/42/console
):

[ERROR] /home/hudson/hudson-slave/workspace/HBase-TRUNK-on-Hadoop-23/trunk/src/main/java/org/apache/hadoop/hbase/util/FSHDFSUtils.java:[35,38]
cannot find symbol
[ERROR] symbol  : class FSConstants
[ERROR] location: package org.apache.hadoop.hdfs.protocol
[ERROR]

Cheers
