Hi All,
From last couple of days i am stuck in a problem. I have a query which left
joins 3 drill tables(parquet), everyday it is used to take around 15-20 mins but from last couple of days it is taking more than 45 mins and when i tried to drill down i can see in operator profile that 40% query time is going to PARQUET_WRITER and 28% time in PARQUET_ROW_GROUP_SCAN. I am not sure if before this issue the stats were same or not as earlier it gets executed in 15-20 min max.Also on top of this a table, we used to create a table which is now showing below error :- SYSTEM ERROR: BlockMissingException: Could not obtain block: BP-1083556055-10.51.2.101-1481111327179:blk_1094763477_21022752 Also in last few days i am getting frequent one or more node lost connectivity error. I just upgraded to Drill 1.12.0 from 1.10.0 but above issues are still there. Any help will be appreciated. Regards, Anup Tiwari
