fastparquet created parquet file
[ https://issues.apache.org/jira/browse/DRILL-5430?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15969463#comment-15969463 ]
Kunal Khatua commented on DRILL-5430:
-------------------------------------
Can you read the file using parquet-tools ?
I could not:
[root@node1 ~]# parquet-tools schema /tmp/delMe/frmPandas_9.parquet
message schema {
required int32 c_int8_signed (INT_8);
required int32 c_uint8 (UINT_8);
}
[root@node1 ~]# parquet-tools meta /tmp/delMe/frmPandas_9.parquet
file: file:/tmp/delMe/frmPandas_9.parquet
