Fixed Issues in Phoenix

Review the list of Phoenix issues that are resolved in Cloudera Runtime 7.1.9 SP1.

CDPD-69580: Backport of PHOENIX-6687

This is a backport of PHOENIX-6687 - the region server hosting the SYSTEM.CATALOG file fails to serve any metadata requests as the default handler pool threads are exhausted.

CDPD-60862: DDL refers to "Data Definition Language", a subset of SQL statements that change the structure of the database schema in some way, typically by creating, deleting, or modifying schema objects such as databases, tables, and views. Cloudera services that support DDL include Impala, Hive (using HiveQL), Spark (using SparkSQL), HBase, Phoenix, Flink, and Kafka.

This issue is fixed.

CDPD-35925: Omid service fails to start rarely. Restarting it solves the problem most of the times.

This issue is fixed.
