--------------------------------
Summary: Fix application dependencies on mutually exclusive
artifacts: tez-yarn-timeline-history and tez-yarn-timeline-history-with-acls
Key: TEZ-2168
URL: https://issues.apache.org/jira/browse/TEZ-2168
Project: Apache Tez
Issue Type: Bug
Reporter: Hitesh Shah
Feedback from Chris Wensel on dev list related to simplifying the build file
for an app dependent on Tez.
Currently, based on hadoop versions, one needs to choose between mutually
exclusive artifacts: tez-yarn-timeline-history and
tez-yarn-timeline-history-with-acls.
Suggested options:
create a single artifact tez-yarn-timeline-history compiled with a default dep
of hadoop 2.6, that includes the Manager. update the TezClient code to
gracefully fail if the Manager is not applicable (the runtime env is Hadoop
2.4).
or
offer tez-yarn-timeline-history-with-acls as an optional artifact for Hadoop
2.6 deployments, with the single Manager class in it, which in turn requires
the tez-yarn-timeline-history artifact -- which is sufficient for a 2.4
runtime. if the user provides the additional -with-acls artifact, they are
knowingly going to have problems on Hadoop 2.4.
