> The snapshotDiff command fails if the snapshotDiff report size is larger than
> the configuration value of ipc.maximum.response.length which is by default
> 128 MB.
> Worst case, with all Renames ops in sanpshots each with source and target
> name equal to MAX_PATH_LEN which is 8k characters, this would result in at
> 8192 renames.
>
> SnapshotDiff is currently used by distcp to optimize copy operations and in
> case of the the diff report exceeding the limit , it fails with the below
> exception:
> Test set:
