----------------------------------
Summary: Isolate Curator Dependencies
Key: METRON-2261
URL: https://issues.apache.org/jira/browse/METRON-2261
Project: Metron
Issue Type: Sub-task
Reporter: Nick Allen
Assignee: Nick Allen
As part of the HDP 3.1 upgrade, we need to upgrade to Curator 4.x. [There was
a discuss thread
|[https://lists.apache.org/thread.html/265a76f6071229af662135b92df6db652d8ee2b17dbec8af7e8bf1ba@%3Cdev.metron.apache.org%3E]]
covering the need for this.
Currently, Curator is being pulled in as a transitive of Hadoop, HBase and
Storm. At the current versions this does not cause a problem. But when
upgrading Hadoop, different conflicting versions of Curator will get pulled in.
We need to ensure that only a single version of Curator is pulled in after
upgrading Hadoop. This change will maintain the current versions in use
including Curator 2.7.1 and Zookeeper 3.4.6.
In upgrading to Curator 4.x, there is a breaking change that causes the
MaasIntegrationTest to fail. The fix for that, plus the actual upgrade to
Curator 4.x will be performed under a separate Jira to aid the review process.
