[jira] [Commented] (IMPALA-6772) Enable test_scanners_fuzz for ORC format

    [ https://issues.apache.org/jira/browse/IMPALA-6772?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16643291#comment-16643291 ] 

Quanlong Huang commented on IMPALA-6772:
----------------------------------------

Linking with the ORC lib built in DEBUG mode, I was able to run orc fuzz-test for 3 days without any crash. Unfortunately, when linking with ORC lib built in RELEASE mode, I found a crash which due to ORC-414. This may need to redesign protobuf definitions of ORC by introducing some checksums, which takes some times.

> Currently, we haven't enabled test_scanner_fuzz for ORC yet, since the ORC library (release-1.4.3) is not robust for corrupt files (ORC-315). We should enable it after a new version of the ORC library is released.
