Snehal Waghmare commented on FLUME-3137:
----------------------------------------
Temporarily we are moving files continuously from the processed folder to as to
prevent the bulk pushing of the data.
Also, updated the JAVA_OPTS configuration with following configuration:
"-Xms2000m -Xmx16000m -Xss128k -XX:MaxDirectMemorySize=256m -XX:+UseParNewGC
-XX:+UseConcMarkSweepGC -XX:-UseGCOverheadLimit"
Kindly help me solve the above issue.
