> Key: HDDS-2334
> URL: https://issues.apache.org/jira/browse/HDDS-2334
> Project: Hadoop Distributed Data Store
> Issue Type: Bug
> Components: test
> Reporter: Attila Doroszlai
> Assignee: Attila Doroszlai
> Priority: Major
>
> HDDS-1094 added a config option ({{hdds.container.chunk.persistdata=false}})
> to drop chunks instead of writing them to disk. Currently this option
> triggers the following error with any key size:
> {noformat}
> org.apache.hadoop.hdds.scm.container.common.helpers.StorageContainerException:
> data array does not match the length specified. DataLen: 16777216 Byte
> Array: 16777478
