GP - Kerberos errors and resolutions

Issue:1. Ticket granting has expired with the error message, ERROR: psql: GSSAPI continuation error: Unspecified GSS failure. The Minor code may also display the error message, GSSAPI continuation error: Ticket expired. Solution: Create a new ticket on the Master server using the following command: kinit -k -t /home/gpadmin/gpdb-kerberos.keytab db_user Note: -t is the keytab file and db_user is the user. Issue:2. The library required to run the kinit command does not exist in the LD_LIBRARY_PATH  set in the Greenplum binaries, producing the following error message: ERROR: kinit: relocation error: kinit: symbol krb5_get_init_creds_opt_set_fast_ccache_name, version krb5_3_MIT not defined in file libkrb5.so.3 with link time reference Solution: Unset the LD_LIBRARY_PATH. IMPORTANT NOTE: The above fix will cause the following error when you try to run Postgres commands:  ERROR: psql: error while loading shared libraries: libpq.so.5: cannot open shared object ...

GP - SQL Joins

Available Join Types? Row Elimination Minimize Data Movement Join Implementation Seen in Query Plans Join Types: Inner Join Resulting data set is obtained from joining two tables on a common column Each row in left table is compared with each row in right table Matching rows will be present in result set Most commonly used Also know has Simple Join or EQUI-Join Left Outer Join Returns all rows from the left table even if there is no matching rows in right table. Will also get the matching rows Rows that are not matched in the right table will not be included in the result set Right Outer Join This is similar to left outer join, just need to flip the join Full Outer Join Will return all rows from both the tables where there is a match We will receive a NULL for rows which don’t match Cross Join Which is also called has Cartesian products Result set will have all rows on the left table paired with all rows on the right table Exam...
