The changes require that Hadoop be uninstalled and reinstalled. The conf directory, configuration files, is now copied to the local_hadoop/traf_conf directory by Hadoop installation script.
Zalo -----Original Message----- From: Dave Birdsall <[email protected]> Sent: Wednesday, September 11, 2019 5:59 PM To: [email protected] Subject: A heads-up about a recent pull request External Hi, I recently merged a pull request: https://github.com/apache/trafodion/pull/1854 I'm noticing one side effect from this pull request. I had a successful Trafodion development instance, using local Hadoop, based on code before this pull request. I did an sqstop + swstophbase. Then I did a git fetch origin, picking up Zalo's change, then created a new branch and did a make clean + make all. Then I did swstarthbase. Hbase comes up successfully. When I do an sqstart however, it hangs at 5 processes and never comes up. An sqps command fails with: [birdsall@edev05 trafodion]$ sqps 2019-09-11 23:47:54,, FATAL, TRAFCONFIG,,, PIN: 17917,,,, TID: 17917, Message ID: 101091501, [CClusterConfig::CClusterConfig], Environment variable TRAF_CLUSTER_ID is undefined, exiting! So I did a pkillall. I then did an sqgen, followed by another attempt at sqstart. It still hangs at 5 processes. I noticed that sqgen did not recreate ms.env, which is where environment variables are defined. So I tried deleting it, and doing sqgen + sqstart again. Didn't help, same hang. I noticed something else. When running sqgen, I see: Can't open /mnt2/birdsall/trafodion/core/sqf/sql/local_hadoop/traf_conf/sqconfig.persist: No such file or directory at ./gensq.pl line 606, <> line 12. So, perhaps I need to blow away my instance and reinstall local_hadoop. So, I tried pkillall + git clean -fxd + make all + install_local_hadoop + install_traf_components + sqgen + sqstart. That's in progress now; will let you know how it turns out. So this e-mail is just a heads-up that this particular change seems to require a fresh install. I notice that Jenkins Trafodion tests are running fine, so clean installs should work. Dave
