    Description

      Our cluster is consisting of about 60 Impala nodes. After a period of time and after executing some "heavy" queries the performance of the cluster becomes bad and the Impala is not responding after a period of time. We observed that day after day the Impala Resident memory and the running threads of the machine keep growing even if we do not run queries. Everytime we perform an Impala restart everything seems to work fine for a period of time.
