[jira] [Commented] (PARQUET-1012) parquet-cpp and parquet-mr version parse inconsistent

["Deepak Majeti (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PARQUET-1012?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16035485#comment-16035485 ] 

Deepak Majeti commented on PARQUET-1012:
----------------------------------------

I could not reproduce this with parquet-mr 1.8.2.
The error seems to originate from {{shouldIgnoreStatistics}} in {{parquet-column/src/main/java/org/apache/parquet/CorruptStatistics.java:52}}.
I added a test in {{parquet-column/src/test/java/org/apache/parquet/CorruptStatisticsTest.java}} with the {{parquet-cpp version 1.0.0}} string and it works fine.
Can you share the parquet-cpp file?

> Spark 2.1 uses parquet-mr(common) 1.8.2 which requires created_by to match certain pattern.  I found the following exception when using spark to read parquet file generated by parquet-cpp.
> 17/05/31 16:33:53 WARN CorruptStatistics: Ignoring statistics because created_by could not be parsed (see PARQUET-251): parquet-cpp version 1.0.0
> org.apache.parquet.VersionParser$VersionParseException: Could not parse created_by: parquet-cpp version 1.0.0 using format: (.+) version ((.*) )?\(build ?(.*)\)
> Proposal to fix this issue:  set created_by to the certain pattern.
