How to notice if this is a problem
* The dataset will not download when using the disk icon * Tools error when using a specific dataset that has been used before successfully * Tools error with a message that ends with: `OSError: [Errno 2] No such file or directory`. Note that not all failures of this type are due to metadata and may simply be a cluster failure - rerunning the job may resolve the problem instead, but try the solution first.
* Reset the metadata on the dataset(s). This may be an uploaded dataset or one created by prior tools. It could be one of the input datasets to a failed job. * Directly reset metadata: click on the the dataset's ![pencil](/images/icons/pencil.png "pencil") icon, then click into the _Dataype_ tab and reset to the correct format. Don't forget to save! The dataset will turn yellow in the history while the job is processing. * Autodetect: click on the dataset's ![pencil](/images/icons/pencil.png "pencil") icon, cthen lick on the _**Auto-detect**_ button found near the bottom of the _**Edit Attributes**_ form. The dataset will turn yellow in the history while the job is processing.
If this does not resolve the problem
* If resetting metadata does fix the issue, then there may have been a transient cluster job failure. Re-run the job at least once.
