Hi Vikash,

Could you try if Alluxio CLIs (e.g. copyFromLocal) work well with your Alluxio with Mapd?

Thanks,
Lu

Re: Alluxio Fuse failed to create file

Hi Vikash,

If files are not written to under filesystem through Alluxio, Alluxio will not contain the metadata of those files and possible parent directories. In this case, ./bin/alluxio fs ls /path command will check if /path exists in Alluxio metadata. If not, ls command will try to load metadata of the /path from the under filesystem. If -f option is given, it forces loading metadata for immediate children in a directory. By default, it loads metadata only at the first time at which a directory is listed.

I haven't seen your error of Alluxio Fuse MapR mount before, so we may need to understand MapR under storage better to help solve this problem. I added a comment at your MapR jira https://alluxio.atlassian.net/browse/ALLUXIO-3337 to record this error. Please add more detailed information if possible.

Thanks,
Lu
