Hi!
I'm running into this stack when trying to read through IGFS to an
underlying HDFS instance:
java.lang.NullPointerException
at
org.apache.ignite.internal.processors.hadoop.impl.igfs.HadoopIgfsInputStream$FetchBufferPart.flatten(HadoopIgfsInputStream.java:458)
at
org.apache.ign
performance. Specifying
sequentialReadsBeforePrefetch = 32 sometimes gives me buffer underflow
issues when trying to parse data out of the file format.
Thanks!
Joe

Joe,
It seems a bug, I've filed a ticket [1]. Could you please check if this
problem exists in 1.8 version?

Thanks!

Yes--we were experiencing this in 1.8 before upgrading to 1.9.

Hi,
Thanks for testing, hadoop specialists will fix it. Please use
sequentialReadsBeforePrefetch = 64 as a workaround for now.
Thanks!
