Hi, I'm running hive 0.12 on yarn and I'm trying to convert a common join into a map join. My map join fails and from the logs I can see that the memory limit is very low:
Starting to launch local task to process map join; maximum memory = 514523136 How can I increase the maximum memory? I've set the HADOOP_HEAP_SIZE at 7GB in hadoop-env.sh and hive-env.sh but that didn't help. Also the nodemanager runs with 7GB heap size. Is there anything else I can do to increase this value? Thanks, Avrilia
