------------------------------------------
I see couple of issues around the compute stats for impala tables on top of
Hive-4.
{code:java}
org.apache.thrift.protocol.TProtocolException: Required field 'engine' is
unset!
Struct:SetPartitionsStatsRequest(colStats:[ColumnStatistics(statsDesc:ColumnStatisticsDesc(isTblLevel:true,
dbName:tpcds_10000_parquet, tableName:t12, catName:hive),
statsObj:[ColumnStatisticsObj(colName:a1, colType:int,
statsData:<ColumnStatisticsData longStats:LongColumnStatsData(numNulls:0,
numDVs:1)>)])], needMerge:false, engine:null)
