Hi Kylin users/developers Kylin 2.3.0, hadoop 2.6.5 cdh 5.12 A error occurred when I built a cube at step 2 Redistribute Flat Hive Table. I checked the MR log and the log shows that reducers containers is running beyond physical memory limits below is detail logs: Diagnostic Messages for this Task: Container [pid=50920,containerID=container_1518617687620_384770_01_000287] is running beyond physical memory limits. Current usage: 1.0 GB of 1 GB physical memory used; 2.6 GB of 2.1 GB virtual memory used. Killing container.
then I try to overwrites the related config kylin.engine.mr.config-override.mapreduce.reduce.memory.mb = 4096 kylin.engine.mr.config-override.mapreduce.reduce.java.opts = -Xmx3g then built the cube again, the the same error came again. I check the yarn config mapreduce.reduce.memory.mb = 2G. this time I'm fully confused. where kylin get the 1GB physical memory config limit? why the overwrites not work? -- BR Xixin
