------------------------------------
Summary: Change port range of TEZ's web UI server after TEZ-4347
Key: IMPALA-11498
URL: https://issues.apache.org/jira/browse/IMPALA-11498
Project: IMPALA
Issue Type: Task
Components: Frontend
Reporter: Fang-Yu Rao
Assignee: Fang-Yu Rao
After TEZ-4347, by default TEZ would attempt to start a web UI server
before opening a session. The default port range for the server
specified in
[TezConfiguration.java|https://github.infra.cloudera.com/CDH/tez/blob/cdw-master/tez-api/src/main/java/org/apache/tez/dag/api/TezConfiguration.java#L1823]
(in the TEZ repository) is
"50000-50050", which does not seem to be a good choice in Impala's
testing environment in that there are always some other client programs
holding those ports when TEZ attempts to start its web UI server. As a
result, TEZ could not bind a port in the port range to start its web UI
server, resulting in TEZ session not being created.
We should specify a better port ranger for TEZ once we start using a TEZ
dependency with TEZ-4347.
