Hi, We are facing performance issue where apache drill query on ecs time out with below error "ConnectionPoolTimeoutException: Timeout waiting for connection from pool"
However same query works fine on hdfs single node with execution time of 2.1 sec.(planning =.483s) Parquet file size <1.5 GB Total parquet files scanned = 8( total 19 in directory) Apache drill version 1.17 JDK 1.8.0_74 Total rows returned from query =71000 There are 2 drillbits running in distributed mode . 13 GB default allocated per drill bit. Any ideas why ecs performance so bad when compared with hdfs for drill ? Please advise if drill provides options to optimize ecs querying . Please let me know if you need more details. Thanks & Regards, Navin
