Mukul Kumar Singh created HDFS-12337:
----------------------------------------
Summary: Ozone: Concurrent RocksDB open calls fail because of "No
locks available"
Key: HDFS-12337
URL: https://issues.apache.org/jira/browse/HDFS-12337
Project: Hadoop HDFS
Issue Type: Sub-task
Components: ozone
Affects Versions: HDFS-7240
Reporter: Mukul Kumar Singh
Assignee: Mukul Kumar Singh
Fix For: HDFS-7240
HDFS-12216 fixes the issue with the static container cache and re-using the
same container port on datanode restart. However TestKeys still fails after
HDFS-12216 is fixed.
The test is now failing because Concurrent RocksDB open calls fail. In the
current code BlockDeleting service and Dispatcher tries to open the db
concurrently.
This jira will also fix the keepPort property for Ratis Container port and set
the reuse address property for XceiverServerRatis correctly.
