I tried slider create <> --metainfo metainfo.json and other flags. It gave
following trace

I am on version **** 0.80 ****
The metainfo.json contents are
{
"metainfo": {
"schemaVersion": "2.0",
"application": {
"name": "ms_no_meta",
"comment": "ms_no_meta Memcached service deployed by Slider",
"version": "1.0.0",
"type": "YARN-APP",
"exportedConfigs": "None",
"minHadoopVersion": "2.6.0",
"osSpecifics": {
"osSpecific": {
"osType": "any",
"packages": {
"package": {
"type": "tarball",
"name": "files/jmemcached-1.0.0.tar"
}
}
}
}
}
}
}
Any help will be appreciated ...
