Environment
- KRB5_TRACE only works on Kerberos 1.9.0+.
- HAWQ 1.1.4 and above
Question:
How to enable kerberos trace logging with HAWQ database to identify any kerberos issue?
Solution:
Step 1: Edit /usr/local/hawq/greenplum_path.sh file to include the below entry:
export KRB5_TRACE=<File Name>
Note: Do not use /dev/out instead of filename above, it will slow down the initialization process and also, messages would not be available for future references
Enabling KRB5_TRACE will send tracing information for kinit to the specified file.
Step 2: Source greenplum_path.sh file
source /usr/local/hawq/greenplum_path.sh
Step 3: Restart HAWQ database
Now you can refer to the file created and review any kerberos errors encountered.
