Story #3375
Updated by Chris Jones about 12 years ago
We've seen a number of issues in each environment where Metacat's PostgreSQL system metadata tables don't stay in sync, replication suffers from inconsistent replica statuses across CNs, and the hzIdentifiers set iterator inconsistently won't iterate through the entire Set. One major factor may be Hazelcast cluster instance communication problems, showing up in the catalina.out logs as:
<pre>
WARNING: /64.106.40.7:5701 [DataONE] hz.1.InThread Closing socket to endpoint Address[160.36.13.152:5701], Cause:java.io.EOFException
</pre>
These are known issues in the Hazelcast forum and issue list for 1.9.X, and the recommended recommemded fix is to upgrade to Hazelcast 2.X, where the connection framework has been significantly rewritten. This story documents the components that need to be modified to handle the 2.X API changes.
