Yiqun,
Is this related to HDFS-9260?
Note that HDFS-9260 was backported since CDH5.7 and above.
I'm interested to learn more. Did you observe clients failing to close file
due to insufficient number of block replicas? Did NN fail over?
Did you have gc logging enabled? Any chance to take a heap dum
Are you using CMS? How big is young gen?
How often does the NN do young gen collection when it is slow?
