Some clarifications:
-
DREMIO_PID_DIRonly changes the destination directory fordremio.pidfile (which is used to keep track of running Dremio process. - By default,
java_pid<id>.hprofare written underDREMIO_LOG_DIR. - Those files are memory dump files, not pid files (they contain pid in their name because the id is the process id of the process whose file originated from). They are debugging information, totally safe to remove.
