For a full list of upstream JIRAs fixed in CDH 5.8.4, see the issues fixed section of the Release Notes.
- Cloudera Manager fixes for the following issues:
- Dollar sign ($) character in password results in IllegalArgumentException: Using special characters such as the dollar sign ($) for passwords and other user-supplied values with CSD-based services (those added to Cloudera Manager with custom service descriptors) raised exceptions. This has been resolved.
- Hive replication command should update copy the SerDe properties correctly: Hive replication now replicates the SerDe properties and also copies the corresponding HDFS file.
