Todd Lipcon created HIVE-21649: ---------------------------------- Summary: Passing an non-existent jar in HIVE_AUX_JARS_PATH produces incorrect error message Key: HIVE-21649 URL: https://issues.apache.org/jira/browse/HIVE-21649 Project: Hive Issue Type: Bug Components: Tez Reporter: Todd Lipcon
I had configured HS2 with HIVE_AUX_JARS_PATH pointing to a non-existent postgres jar. This resulted in queries failing with the following error: {code} tez.DagUtils: Localizing resource because it does not exist: file:/data/1/todd/impala/fe/target/dependency/postgresql-42.2.5.jar to dest: hdfs://localhost:20500/tmp/hive/todd/_tez_session_dir/9de357d5-59bf-4faa-8973-5212a08bc41a-resources/postgresql-42.2.5.jar tez.DagUtils: Looks like another thread or process is writing the same file tez.DagUtils: Waiting for the file hdfs://localhost:20500/tmp/hive/todd/_tez_session_dir/9de357d5-59bf-4faa-8973-5212a08bc41a-resources/postgresql-42.2.5.jar (5 attempts, with 5000ms interval) tez.DagUtils: Could not find the jar that was being uploaded {code} This incorrect logging sent me on a wild goose chase looking for concurrency issues, HDFS issues, etc, before I realized that the jar in fact didn't exist on the local FS. This is due to some sketchy code which presumes that any IOException is due to a writing conflict. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
