Hello Alex,
We have tried the setup with HDFS and worked fine. The
shared filesstem talked in here
is a Lustre parallel filesystem and is mounted on all the compute
nodes(tasktracker).
The problem as it seems to me is not about different nodes messing up but
temp data written
by one tasktracker on one node and being accessed by another. The dir :
/tmp/hadoop-nazgul/mapred/temp/inject-temp-1557478199/_temporary does exists
on the second node.
