Q. I named my hadoop distribution file hadoop-2.6.0.tgz, but Myriad is trying to download a file named "binary.tgz"
A. Myriad renames the hadoop distro file to binary.tgz
Q. Why do I get this download error?
Download Error
Failed to fetch 'http://localhost:9192/api/artifacts/binary.tgz': Error downloading resource: Failure when receiving data from the peer Failed to synchronize with slave (it's probably exited)
A. This means the binary tar file containing the hadoop distro has not been uploaded to hdfs per this configuration within myriad-config-default.yml:
Tar Files Configuration
servedConfigPath: dist/config.tgz
servedBinaryPath: dist/hadoop-2.6.0.tgz
So, in the case of this configuration example, simply upload the config.tgz file (that contains the etc/hadoop files) and the hadoop-2.6.0.tgz file (contains hadoop distribution being used) into the /dist directory of hdfs.
Q. I have passwordless sudo for the frameworkUser and/or my frameworkUser is root, so why am I getting this error:
sudoless user error
sudo: sorry, you must have a tty to run sudo
A. This means the sudoers file default is set requiring a tty session as detailed here. To fix, do the following:
sudo su root visudo #Comment or delete the following line: Defaults requiretty
