CDH 5.2 Impala query fails with llama exception RESERVATION_ASKING_UNKNOWN_NODE

New Contributor

Trying to get Impala working under CDH 5.2 (was working fine under CDH 5.1.3). Can query hbase table via hive fine (and was fine using Impala under CDH 5.13) but run do same query (SELECT * FROM <table>) using Impala (via 'Hue) under CDH 5.2 now, get the following Llama related error - any clues what is wrong/how to get this working ? The node (lo1-qdw-fi-9) is the host on which all the impala services (including the impala daemon) are running and all are reported green in CM.
