Sahil Takiar commented on HIVE-16402:
-------------------------------------

RB: https://reviews.apache.org/r/58283/

* Updated Hadoop version to 2.8.0 in a few different places
* Had to declare explicit dependencies on a few Hadoop libraries because other 
dependencies were pulling in old versions
* Fixed some of the transitive dependencies on slf4j-log4j12

Failed tests are flaky:

HIVE-16313 - TestBeeLineDriver.testCliDriver[drop_with_concurrency]
HIVE-16320 - TestBeeLineDriver.testCliDriver[escape_comments]
HIVE-15776 - TestMiniLlapLocalCliDriver.testCliDriver[vector_if_expr]
HIVE-16410 - TestTxnCommands2.testSimpleRead
HIVE-16381 - TestJdbcDriver2.testResultSetMetaData

> Hadoop 2.8.0 has been out since March, we should upgrade to it. Release notes 
> for Hadoop 2.8.x are here: http://hadoop.apache.org/docs/r2.8.0/index.html
> It has a number of useful features, improvements for S3 support, ADLS 
> support, etc. along with a bunch of other fixes. This should also help us on 
> our way to upgrading to Hadoop 3.x (HIVE-15016).
