Prasanth J commented on HIVE-5502:
----------------------------------
[~brocknoland] I think this is because of the difference in JVM heap size. More
JVM heap size will generate lesser number of stripes and hence the file dump
information will be less. Can you please try using the same heap size (probably
with same ANT_OPTS and MAVEN_OPTS) and see if this issue happens again?
