Subject [jira] [Commented] (DRILL-2616) strings loaded incorrectly from parquet files
Date Mon, 30 Mar 2015 16:04:54 GMT

    [ https://issues.apache.org/jira/browse/DRILL-2616?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14386904#comment-14386904

Jason Altekruse commented on DRILL-2616:

Does a select star produce this problem for you? I tried reading the file both with the standard
parquet java implementation tools (https://github.com/apache/incubator-parquet-mr/tree/master/parquet-tools)
and Drill and it didn't look like any of the data was out of place from inspecting the data
in each column visually. Could you post a query along with the incorrect output you are seeing?
