We are pleased to announce the release of Cloudera Enterprise 5.4.5 (CDH 5.4.5, Cloudera Manager 5.4.5, and Cloudera Navigator 2.3.5).

    • Predicate push-down does not work with Parquet when partitions are in the expression.

    • Impala DML/DDL operations corrupt table metadata leading to Hive query failures.
    • Reserved RBW space is not released if the client terminates while writing a block.

    • NullPointerException on queries where MapReduce is not involved on tables with partitions.

    • Parallel move task optimization causes a race condition.

    • ResultSerialization and MutationSerialization can throw InvalidProtocolBufferException when serializing a cell larger than 64 MB.

For a full list of upstream JIRAs fixed in CDH 5.4.5, see the issues fixed section of the Release Notes.

  • Cloudera Manager fixes for the following issues:

    • Cancel Impala Query attempts to connect via SSL despite SSL being disabled.
