Known issues in 7.1.9 CHF 6
You must be aware of the known issues and limitations, the areas of impact, and workaround in Cloudera Runtime 7.1.9 CHF 6.
- After upgrading the cluster from CDP Private Cloud Base 7.1.8 to CDP Private Cloud Base 7.1.9 and Ozone is in the Non-HA environment, an exception message is observed during the finalization of the Ozone upgrade.
- During the finalization of the upgrade, ClassNotFoundException for org.cloudera.log4j.redactor.RedactorAppender class was identified. The error message is harmless as the upgrade is successful. The error existed previously and does not affect the Ozone service and its operation.
- When using S3A committer fs.s3a.committer.name=directory with fs.s3a.committer.staging.conflict-mode=replace to write to FSO buckets, the client fails with the following error.
DIRECTORY_NOT_FOUND org.apache.hadoop.ozone.om.exceptions.OMException: Failed to find parent directory of xxxxxxxx at org.apache.hadoop.ozone.om.request.file.OMFileRequest.getParentID(OMFileRequest.java:1008) at org.apache.hadoop.ozone.om.request.file.OMFileRequest.getParentID(OMFileRequest.java:958) at org.apache.hadoop.ozone.om.request.file.OMFileRequest.getParentId(OMFileRequest.java:1038) at org.apache.hadoop.ozone.om.request.s3.multipart.S3MultipartUploadCompleteRequestWithFSO.getDBOzoneKey(S3MultipartUploadCompleteRequestWithFSO.java:114) at org.apache.hadoop.ozone.om.request.s3.multipart.S3MultipartUploadCompleteRequest.validateAndUpdateCache(S3MultipartUploadCompleteRequest.java:157) at org.apache.hadoop.ozone.protocolPB.OzoneManagerRequestHandler.handleWriteRequest(OzoneManagerRequestHandler.java:378) at org.apache.hadoop.ozone.om.ratis.OzoneManagerStateMachine.runCommand(OzoneManagerStateMachine.java:568) at org.apache.hadoop.ozone.om.ratis.OzoneManagerStateMachine.lambda$1(OzoneManagerStateMachine.java:363) at java.base/java.util.concurrent.CompletableFuture$AsyncSupply.run(CompletableFuture.java:1700) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628) at java.base/java.lang.Thread.run(Thread.java:834)

- CDPD-66247: TestOzoneFileSystem.testListStatusOnKeyNameContainDelimiter is intermittent
- None
- OPSAPS-69539 : CDP Runtime 7.1.9 does not support Oracle JDK 8u401 or OpenJDK 1.8.0_402 (8u402). Some services will fail to start. This can be a problem on RHEL 9.x as version 8u402 is the default OpenJDK 8 installed by the OS.
- Workaround is to install an earlier version of JDK 8. For example Oracle jdk-8u291 / 1.8.0_291, or OpenJDK 8u292 / 1.8.0_292.
- A fresh install of 7.1.9 CHF 2 does not allow user to bypass the Setup Database screen for YARN Queue Manager
- YARN Queue Manager in Cloudera Data Platform (CDP) Private Cloud Base 7.1.9 CHF 2 does not require you to install a PostGres database, therefore users should be able to skip the Setup Database screen. With this known issue, users who are conducting a fresh install of 7.1.9 CHF 2 are not able to bypass the Setup Database screen as expected.
- CDPD-61524: Ozone Storage Container Manager fails to start on upgrading from CDP Private Cloud Base 7.1.6 to 7.1.9 CHF1. Also, if you have upgraded from CDP Private Cloud Base 7.1.6 to 7.1.7 or 7.1.8 and then to 7.1.9, the upgrade fails.
- None. Cloudera recommends you to reach out to the Support before performing the upgrade to CDP Private Cloud Base 7.1.9.
- CDPD-62254: Ozone is not supported on SLES15 with CHF1.
- If your cluster has Ozone, Cloudera recommends you to not upgrade to 7.1.9 CHF1.
- CDPD-62834: Status of the deleted table is seen as ACTIVE in Atlas after the completion of navigator2atlas migration process
- The status of the deleted table displays as ACTIVE.
- CDPD-62837: During the navigator2atlas process, the hive_storagedesc is incomplete in Atlas
- For the hive_storagedesc entity, some of the attributes are not getting populated.
- CDPD-67651: Recon UI changes for Solr Health Check
- When Solr is slow/down, Solr time to respond to Recon Heatmap query or sometimes does not respond at all. And the Recon heatmap does not load the heatmap data.
