Release 0.4.0 - 2017-09-05
* Split embulk-executor-mapreduce to _2_6 (for Hadoop 2.6.*) and _2_7 (for Hadoop 2.7.*).
Release 0.3.0 - 2017-06-27
* Catch up with a change in Embulk 0.8.24 on PluginType.
Release 0.2.8 - 2016-06-16
* Added local_mode_input_tasks option.
Release 0.2.7 - 2016-04-12
* Shows tracking URL and job ID
Release 0.2.6 - 2016-04-12
* Ignores EOFException when master process reads attempt state files that
can usually happen and safe to ignore.
* Distributing jar files keeps loading order instead of randomizing the order
by hashCode.
Release 0.2.5 - 2016-02-08
* Supports Embulk v0.8.
Release 0.2.4 - 2015-12-21
* Added retry_tasks option
* Added map_side_partition_split option
Release 0.2.3 - 2015-11-11
* If mapreduce.job.user.name is set, executor uses the specified user name to
submit a MapReduce job or accessing to HDFS. This is applicable only when
Hadoop is running in non-secure mode. In secure mode, that user name will be
ignored by HDFS and they use Kerberos instead.
Release 0.2.2 - 2015-10-28
* Remote MapReduce tasks propagate UserDataException. This is useful for
applications to know whether a task failed because of external factors
or user input where retrying doesn't help until user fixes the input.
Release 0.2.1 - 2015-10-26
* Added exclude_jars option
Release 0.2.0 - 2015-08-18
* Upgraded embulk to v0.7.0
* Support for "mapreduce_service_class" system config is removed.
* Added support for "embulk_factory_class" system config.
* Enables JSR 250 Lifecycle support
Release 0.1.5 - 2015-07-28
* Fixed unexpected IllegalStateException and NullPointerException
Release 0.1.4 - 2015-07-23
* Fixed exception at readPluginArchive
* Upgraded required embulk version to v0.6.18
Release 0.1.3 - 2015-07-01
* Fixed a problem where job fails if previous attempt of the same MapReduce
job or task wrote corrupted or empty state file on HDFS.
* Implemented retrying on all methods which include communications to HDFS or
JobTracker.
Release 0.1.2 - 2015-06-27
* Fixed a bug where long value becomes 0 or 1
Release 0.1.1 - 2015-06-22
* Retry reading attempt state file if IOException happens on HDFS
* Added a workaround for "Cannot obtain block length for LocatedBlock"
https://issues.apache.org/jira/browse/HDFS-1058
Release 0.1.0 - 2015-04-07
* The first release.
