chiranjeevi updated HIVE-29169:
-------------------------------
Description:
I have observed Steps to Reproduce :
1) create tez view or TestBeeLineWithArgs#testRowsAffected
was:
The HiveSplitGenerator class incorrectly calculates elapsed time for split
serialization operations, resulting in negative time values in the logs. This
makes debugging and performance analysis difficult.
The calculation fileWriteStarted - Time.monotonicNow() is reversed. Since
Time.monotonicNow() returns the current time, which is always greater than
fileWriteStarted (the time when the operation started), this calculation always
produces a negative number.
