For example &nbsp;-Djute.maxbuffer=100000000<SPAN>&nbsp;in hive-env. The value is just an&nbsp;example, in short you have to bump up the value from the&nbsp;</SPAN>current value. Check the same for ZK as well.&nbsp;</P> Tue, 02 Mar 2021 15:31:05 GMT https://community.cloudera.com/t5/Support-Questions/Beeline-hiveserver2-Error-java-io-IOException-Packet/m-p/312326#M225095 GangWar 2021-03-02T15:31:05Z
