Grant Krieger updated HAWQ-1547: -------------------------------- Description: Hi, Would it be possible to increase incubator-hawq/src/include/pg_config_manual.h property default NAMEDATALEN from 64 to 128. This hopefully will allow one to be able to read Hive tables from Hawq larger than 64 by default without having to change this setting when compiling for downstream systems. It will also allow for equivalently name Hawq tables. Does anyone foresee performance challenges with the increase? See problem below: In hive CREATE TABLE default.test123456789123456789123456789123456789123456789123456789123456789123456789123456789test ( rtlymth int, rtly int) STORED AS ORC in Hawq select * from hcatalog.default.test123456789123456789123456789123456789123456789123456789123456789123456789123456789test ERROR: remote component error (500) from '127.0.0.1:51200': type Exception report message NoSuchObjectException(message:default.test12345678912345678912345678912345678912345678912345678912345 table not found) description The server encountered an internal error that prevented it from fulfilling this request. exception javax.servlet.ServletException: NoSuchObjectException(message:default.test12345678912345678912345678912345678912345678912345678912345 table not found) (libchurl.c:897) Position: 15 Line: 1 Thanks Grant was: Hi, Would it be possible to increase incubator-hawq/src/include/pg_config_manual.h property default NAMEDATALEN from 64 to 128.
