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 has been lost. About the CPU LOAD, NETWORK TRAFFIC I have no info. Any pointers about where do I have look for the problem's root ? Today I'm trying to repeat the problems I got with DO/WHILE, nothing bad is happening although CPU LOAD is enough high and NETWORK TRAFFIC increased up to 282 Kb/sec. Of course I can redo the "ls -R /" on production, however I like to avoid it since there are already some ingestion flows running. AP
