Xiao Chen commented on HDFS-9314: --------------------------------- Thanks [~djp] and [~mingma]. The failed tests in patch 5 are not related. I have locally run the tests which appeared to be failing on both (intersect) JDK 7 & 8, and all of that passed. The environment seems to be having problems as there's a lot of timeouts in the failures. Also a couple of flaky tests such as HDFS-9300. > Improve BlockPlacementPolicyDefault's picking of excess replicas > ---------------------------------------------------------------- > > Key: HDFS-9314 > URL: https://issues.apache.org/jira/browse/HDFS-9314 > Project: Hadoop HDFS > Issue Type: Improvement > Reporter: Ming Ma > Assignee: Xiao Chen > Attachments: HDFS-9314.001.patch, HDFS-9314.002.patch, > HDFS-9314.003.patch, HDFS-9314.004.patch, HDFS-9314.005.patch, > HDFS-9314.006.patch > > > The test case used in HDFS-9313 identified NullPointerException as well as > the limitation of excess replica picking.
