Subject Re: [Virtual MEETUP]: Migration to Hadoop 3
Date Wed, 26 Aug 2020 17:50:48 GMT
One more update from me.

We didn't face any issues with YARN, for HDFS you can have a look at the
following jira's.

https://issues.apache.org/jira/browse/HDFS-13596
https://issues.apache.org/jira/browse/HDFS-14396
https://issues.apache.org/jira/browse/HDFS-14509

Following jira is incompatible for ACL commands.Only hadoop-3 clients will
work against hadoop-3 server during the upgrade.

https://issues.apache.org/jira/browse/HDFS-6984
