For a full list of upstream JIRAs fixed in CDH 5.7.6, see the issues fixed section of the Release Notes.
Cloudera Manager fixes for the following issues:
- Dollar sign ($) char in password results in IllegalArgumentException: Using special characters such as the dollar sign ($) 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.
- Cloudera Manager server error - JsonMappingException: Fixed an issue where a race condition can happen when getting the log links for unhealthy roles and then cause a null pointer exception for the Cloudera Manager homepage.
