FAQ
The HBase team is pleased to announce the second [zero-indexed] release
candidate for HBase 0.90.1, available for download at the following URL:
http://people.apache.org/~todd/hbase-0<http://people.apache.org/~todd/hbase-0.90.1.rc0/>
- HBASE-3515 [replication] ReplicationSource can miss a log after RS
comes
<http://people.apache.org/~todd/hbase-0.90.1.rc0/>
- out of GC
.90.1.rc1/ <http://people.apache.org/~todd/hbase-0.90.1.rc0/>

This release candidate addresses a couple of bugs since the last release
candidate:
HBASE-3524 NPE from CompactionChecker
HBASE-3525 mvn assembly is over-filling the hbase lib dir
HBASE-3531 When under global memstore pressure, dont try to flush
unflushable regions.


The following is the md5sum:
dbf090fcb12a47c0b6c713c3caa7b1fd hbase-0.90.1.tar.gz
and it corresponds to the 0.90.1RC1 tag at r1070711.

<http://people.apache.org/~todd/hbase-0.90.1.rc0/>HBase 0.90.1 is a minor
release containing important bug fixes and low-risk improvements since
HBase 0.90.0. The following is a complete list of tickets resolved for this
minor release:

https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12310753&version=12315548

As a minor release, no migration procedures are necessary to upgrade from
0.90.0. Additionally, no public facing APIs should differ in any way. If you
are upgrading from a previous major release, some caveats may apply - please
see the relevant documentation for details. All users of 0.90.0 are advised
to upgrade at their earliest convenience.

Please vote by Thurs 2/17 whether we should release this artifact as HBase
0.90.1. PMC votes are binding, non-PMC votes are as always very much
appreciated!

Thanks
The HBase Team

    Downloaded, reviewed doc., and checked it runs locally.

    Put it up on cluster, ran some YCSBs -- I deployed a snapshot of RC1
    to apache maven snapshot repo with name 0.90.1-20110215.213202-4 if
    anyone needs it -- and all seemed to run fine in basic write and
    read/write scenarios. Review of logs turned up no exceptions.

    I ran rowcounter to make sure MR works as documented.

    +1. On a 5 node test cluster, loaded 100M rows (~170G on disk) using YCSB,
    did some mixed workload (increment, scan, read, put). No GC pauses. Killed a
    server while under load, recovered correctly.

    Along the way I accidentally deleted my ZK jar while the cluster was
    running, which left a couple regions unassigned. hbck -fix fixed them.

    Also, the new feature that checks for out-of-date hbase-default.xml detected
    that I had left one lying around on the classpath from a previous version,
    so that works! :)

    are upgrading from a previous major release, some caveats may apply - please
    see the relevant documentation for details. All users of 0.90.0 are advised
    to upgrade at their earliest convenience.

    Please vote by Thurs 2/17 whether we should release this artifact as HBase
    0.90.1. PMC votes are binding, non-PMC votes are as always very much
    appreciated!

    Thanks

    With three PMC +1s and no -1s, the vote passes. Thanks for voting!

    Stack and I will undertake the release process tonight/tomorrow and send out
    a formal announcement when the binary is up on the mirrors, etc.

    The HBase team is pleased to announce the second [zero-indexed] release
    candidate for HBase 0.90.1, available for download at the following URL:
    http://people.apache.org/~todd/hbase-0.90.1.rc1/<http://people.apache.org/~todd/hbase-0.90.1.rc0/>

    This release candidate addresses a couple of bugs since the last release
    candidate:
    HBASE-3524 NPE from CompactionChecker
    HBASE-3525 mvn assembly is over-filling the hbase lib dir
    HBASE-3531 When under global memstore pressure, dont try to flush
    unflushable regions.


    The following is the md5sum:
    dbf090fcb12a47c0b6c713c3caa7b1fd hbase-0.90.1.tar.gz
    and it corresponds to the 0.90.1RC1 tag at r1070711.

    <http://people.apache.org/~todd/hbase-0.90.1.rc0/>HBase 0.90.1 is a minor
    release containing important bug fixes and low-risk improvements since
    HBase 0.90.0. The following is a complete list of tickets resolved for
    this minor release:


    https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12310753&version=12315548

    As a minor release, no migration procedures are necessary to upgrade from
    0.90.0. Additionally, no public facing APIs should differ in any way. If
    you are upgrading from a previous major release, some caveats may apply -
    please see the relevant documentation for details. All users of 0.90.0 are
    advised to upgrade at their earliest convenience.

    Please vote by Thurs 2/17 whether we should release this artifact as HBase
    0.90.1. PMC votes are binding, non-PMC votes are as always very much
    appreciated!
