release 0.7.0 export TACHYON_UNDERFS_ADDRESS problem

[DTing]

I am encounter a problem with TACHYON_UNDERFS_ADDRESS in release 0.7.0 that does not occur with release 0.6.4.

 

"tachyon format" fails and "tachyon-start.sh all SudoMount" does not start TachyonMaster with

export TACHYON_UNDERFS_ADDRESS=hdfs://<hostname>:<port #> when the hostname is a long FQDN. It does work when I replace the hostname with a numeric IP address xxx.xxx.xxx.xxx.

Could you share the error message when you failed to run "tachyon format"? thanks

 I was trying to reproduce the error message by replacing the xxx.xxx.xxx.xxx IP address with the original FQDN. However, "tachyon format" and "tachyon-start.sh all SudoMount" now work without any problem. I must not have a clean 0.7.0 environment when I switch from 0.6.4. Sorry for the false alarm.

Never mind, glad to hear it works and thanks for the updates

Sorry about the flip-flopping. I stopped tachyon with "tachyon-stop.sh ", I increased my worker count from 2 to 8 nodes. I synced all the 8 nodes and I encountered the problem again when I execute "tachyon format". The error message is :

When I replaced the FQDN host name with a numeric IP address "tachyon format" and "tachyon-start.sh all SudoMount" ran without failure.
