The Apache HBase team is happy to announce the general availability of HBase 0.90.1, available from your Apache mirror of choice:
http://www.apache.org/dyn/closer.cgi/hbase/ [at the time of this writing, not all mirrors have updated yet -- please pick a different mirror if your first choice does not show 0.90.1] HBase 0.90.1 is a maintenance release that fixes several important bugs since version 0.90.0, while retaining API and data compatibility. The release notes may be found on the Apache JIRA: https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12310753&version=12315548 Users upgrading from HBase 0.90.0 may upgrade clients and servers separately, though it is recommended that both be upgraded. If upgrading from a version of HBase prior to 0.90.0, please read the notes accompanying that release: http://osdir.com/ml/general-hadoop-apache/2011-01/msg00208.html As always, many thanks to those who contributed to this release! -The HBase Team
