Hi,
I'm using Metron 0.4.2 to run pcap_query.sh. From reading the documents, the default output directory is /tmp if -bop is not specified. I tried using default as well as specifying -bop, but I always get Permission denied. If it's trying to write to /tmp, then any user has permission to write. I also checked hdfs /tmp and that's also a true statement that any user can write.
I try to dig into the code, but it's not obvious to me where is it attempting to write the output file. I tried to run as hdfs/metron/storm user, but all ends with the same error. Thank you in advance for your help.
