Vitalii Diravka commented on DRILL-6540:
----------------------------------------
It requires proper Drill's dependency on loggers, currently a lot of logger
transitive dependencies are used, for example {{org.slf4j.LoggerFactory}} is
used from avatica-1.12.0 - resolved.
Also it requires upgrade {{jetty.version}} from 9.1 to at least 9.3 version (it
is used in setting up {{hdfs.MiniDFSCluster}} for Drill unit tests) - resolved.
It requires {{commons-logging}}, which is currently banned in Drill. For some
reason {{Log4JLogger}} is absent in {{jcl-over-slf4j}} - still the issue.
Adapting the code with 2.7-mapr version - resolved.
Work in progress branch - https://github.com/vdiravka/drill/commits/DRILL-6540
> Upgrade to HADOOP-3.1 libraries
> --------------------------------

> Key: DRILL-6540
> URL: https://issues.apache.org/jira/browse/DRILL-6540
> Project: Apache Drill
> Issue Type: Improvement
> Reporter: Vitalii Diravka
> Priority: Major
> Fix For: Future
>
>
> Currently Drill uses 2.7.1 version of hadoop libraries (hadoop-common,
> hadoop-hdfs, hadoop-annotations, hadoop-aws, hadoop-yarn-api, hadoop-client,
> hadoop-yarn-client).
> Half of year ago the [Hadoop
> 3.0|https://hadoop.apache.org/docs/r3.0.0/index.html] was released and
> recently it was an update - [Hadoop
> 3.1|https://hadoop.apache.org/docs/r3.1.0/].
> To use Drill under Hadoop3.0 distribution we need this upgrade. Also the
> newer version includes new features, which can be useful for Drill.
> This upgrade is also needed to leverage the newest version of zookeeper
> libraries.
