Subject [ANNOUNCE] Apache HBase 1.2.7 is now available for download
Date Tue, 25 Sep 2018 22:24:36 GMT
The HBase team is happy to announce the immediate availability of Apache
HBase 1.2.7.

Apache HBase is an open-source, distributed, versioned, non-relational
database. Apache HBase gives you low latency random access to billions of
rows with millions of columns atop non-specialized hardware. To learn more
about HBase, see https://hbase.apache.org/.

HBase 1.2.7 is the latest maintenance release in the HBase 1.2 line,
continuing on the theme of bringing a stable, reliable database to the
Hadoop and NoSQL communities. This release includes over 250
bug fixes done in the 15 months since 1.2.6.

All users of previous 1.2.z releases are encouraged to upgrade to either
this release or the latest in our stable release line, which is currently
1.4.7. Releases in the 1.2.z line are expected to stop in late spring 2019.

Critical fixes include:

* HBASE-18036 Data locality is not maintained after cluster restart
* HBASE-18233 We shouldn't wait for readlock in doMiniBatchMutation in
              case of deadlock
* HBASE-9393  Region Server fails to properly close socket resulting in
              many CLOSE_WAIT to Data Nodes
* HBASE-19924 RPC throttling does not work for multi() with request
              count rater.
* HBASE-18192 Replication drops recovered queues on Region Server
* HBASE-18282 ReplicationLogCleaner can delete WALs not yet replicated
              in case of a KeeperException
* HBASE-19796 ReplicationSynUp tool is not replicating data if a WAL is
              moved to splitting directory
* HBASE-17648 HBase table-level synchronization fails between two
              secured(kerberized) clusters
* HBASE-18137 Replication gets stuck for empty WALs
* HBASE-18577 shaded client should not include non-relocated third party
* HBASE-19900 Region level exceptions destroy the result of batch client
* HBASE-21007 Memory leak in HBase REST server

This release contains the following incompatible changes, details in the
release notes for the specific issue:

* HBASE-20884 Replace usage of our Base64 implementation with java's
* HBASE-18577 shaded client should not include non-relocated third party
* HBASE-18142 delete in HBase shell should not delete previous versions
              of a cell
