Hello all,
yesterday, for a mistake, basically I executed " ls -R / " using the
ListHDFS processor and the whole cluster gone down ( not just a node ).
Something like this also happened when I was playing with some DO WHILE
/ WHILE DO patterns. I have only the nifi logs and they show the
heartbeat

You have two clusters here potentially. The NiFi cluster and the
Hadoop cluster. Which one went down?
If NiFi went down I'd suspect memory exhaustion issues because other
resource exhaustion issues like full file system, exhausted file
handles, pegged CPU, etc.. tend not to cause it to
Hello Witt,
before anything else thanks for your help.
Fortunatly I put down only the NIFI cluster, otherwise I was already in
vacation :)
After I posted this problem I kept to torture staging NIFI and
discovered that when CPU LOAD gets very high, nodes loose connection and
anything starts going
Thanks Adam. I will try 0.7.1 and update the community on the outcome. If
it works then I can create a patch for 1.x
Thanks

Thanks Bryan, Joe, Adam and Pierre. I went past this issue by switching to
0.71. Now it is able to list the files from buckets and create those files
in the another bucket. But write is not happening and I am getting the
permission issue ( I have attached below for the reference) Could this be

Hi,
I'd suggest couple things. Have you configured backpressure controls on
connections? NiFi 1.0.0 adds 1evt/1GB by default IIRC. This can help
avoid overwhelming components in a flow.
Next, the 2 core CPU is really inadequate for high throughput system, see
if you can get something better.
