Nifi is writing the data into PUTHDFS as JSON files. The file permissions and owner of the files are as follows
File_name1 rwx-- nifi:hadoop
There are two things which we don't understand . We do not have Nifi LDAP integrated so far . it runs on default user Nifi.
I cannot ask nifi to change the permission while writing the data or change the owner which is accessible to hive .
We are getting permission denied errors while reading the data from hive . We cannot change the permissions in nifi as it is not added in superusers group . We did tried to add nifi as superusers group . but failed to change the owner information .
How can I write the files which is accessible for both hive and Nifi or how can I change the owner/permissions in nifi after writing the data into HDFS .
You could set the permission of the directory to which PutHDFS is writing to allow group/other read access so that Hive can read that directory, and also set the umask in the PutHDFS processor to write files that are readable by group/other.
