[jira] [Commented] (DRILL-2616) strings loaded incorrectly from
parquet files
[ 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?
