Hello,
I'm trying to use parquet fileformat and it works fine if I write data using Impala and read it in Hive. However, if I insert data to that table via Hive and read it using Impala, Impala will throw errors like:
ERRORS:
Backend 2: Parquet file should not be split into multiple hdfs-blocks
...
It seems that this error is not a fatal one and Impala is able to get the query results, what might be the cause and how to avoid this Error?
Thanks!
