ASF subversion and git services commented on IMPALA-8852: --------------------------------------------------------- Commit 777d0d203f138183d65885b523b619421b487714 in impala's branch refs/heads/master from Tamas Mate [ https://gitbox.apache.org/repos/asf?p=impala.git;h=777d0d2 ] IMPALA-8852: Skip short-circuit config check for dedicated coordinator ImpalaD should not abort when running as dedicated coodinator and DataNode is not available on the host. This change adds a condition to skip the short- circuit socket path directory checks when ImpalaD is started with 'is_executor=false' flag. Testing: - Added test to JniFrontendTest.java to verify the short-circuit directory check is skipped if ImpalaD is started as dedicated coordinator mode. - Manually tested the appearance of the warning message with: start-impala-cluster.py --num_coordinators 1 --use_exclusive_coordinators true Change-Id: I373d4037f4cee203322a398b77b75810ba708bb5 Reviewed-on: http://gerrit.cloudera.org:8080/15173 Reviewed-by: Impala Public Jenkins <impala-public-jenk...@cloudera.com> Tested-by: Impala Public Jenkins <impala-public-jenk...@cloudera.com> > ImpalaD fail to start on a non-datanode with "Invalid short-circuit reads > configuration" > ---------------------------------------------------------------------------------------- > > Key: IMPALA-8852 > URL: https://issues.apache.org/jira/browse/IMPALA-8852 > Project: IMPALA > Issue Type: Bug > Components: Backend > Affects Versions: Impala 3.2.0, Impala 3.3.0 > Reporter: Adriano > Assignee: Tamas Mate > Priority: Major > Labels: ramp-up > > On coordinator only nodes ([typically the edge > nodes|https://www.cloudera.com/documentation/enterprise/5-15-x/topics/impala_dedicated_coordinator.html#concept_omm_gf1_n2b]): > {code:java} > --is_coordinator=true > --is_executor=false > {code} > the *dfs.domain.socket.path* (can be nonexistent on the local FS as the > Datanode role eventually is not installed on the edge node). > The non existing path prevent the ImpalaD to start with the message: > {code:java} > I0809 04:15:53.899714 25364 status.cc:124] Invalid short-circuit reads > configuration: > - Impala cannot read or execute the parent directory of > dfs.domain.socket.path > @ 0xb35f19 > @ 0x100e2fe > @ 0x103f274 > @ 0x102836f > @ 0xa9f573 > @ 0x7f97807e93d4 > @ 0xafb3b8 > E0809 04:15:53.899749 25364 impala-server.cc:278] Invalid short-circuit reads > configuration: > - Impala cannot read or execute the parent directory of > dfs.domain.socket.path > {code} > despite a coordinator-only ImpalaD does not do short circuit reads. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
