Flume Agent that is writing to HDFS is high on virtual memory usage (15.6g). Agent writes to 3 different directories in HDFS based on type of data that is received. Configuration is given below. Any idea why VM usage is high? I see high VM usage only on the Agents that is writing to HDFS. Other Agents are low in VM usage.
Flume version : apache-flume-1.4.0 (I tested with 1.5 version as well).
