Fixed Issues

Review the list of issues that are resolved in the Cloudera Observability On-Premises 3.5.3 release.

OBS-2173: cloudera-sigma-olap directory consumes significant storage space in HDFS: The Cloudera Observability On-Premises 3.5.2 version enables weekly execution of the purger by default. However, periodic clean-up of /cloudera-sigma-olap is not currently included in this purger.
This issue is fixed now by providing a support for purging data from the /cloudera-sigma-olap directory.

OBS-4600: Full log link fails to open the log details page on Mozilla Firefox: On the Spark Job Details page, clicking the Full Log link does not open the Log details page. This issue occurs on Mozilla Firefox.
This behavior is resolved now. You can now view the Log details page.

OBS-5246: Workload alerts missing or Kafka connection error in Admin API logs with TLS enabled

Admin API server starts, however, the following warning is displayed in the role logs:

WARN org.apache.kafka.clients.NetworkClient: [kafka-producer-network-thread | producer-1] [Producer clientId=producer-1] Connection to node -1 (example-1.esc12345.root.comops.site/192.0.2.0:24) terminated during authentication. This may happen due to any of the following reasons: (1) Authentication failed due to invalid credentials with brokers older than 1.0.0, (2) Firewall blocking Kafka TLS traffic (eg it may only allow HTTPS traffic), (3) Transient network issue.
WARN org.apache.kafka.clients.NetworkClient: [kafka-producer-network-thread | producer-1] [Producer clientId=producer-1] Bootstrap broker example-1.esc12345.root.comops.site:24 (id: -1 rack: null) disconnected

This issue occurs when SSL Truststore path (JKS) and password are not configured for the Admin API Server component.

This issue is fixed now.
