> There are some cases of space quota that need to be tested for heterogenous
> storages. It's quite important to ensure space quota works well in modern
> clusters typically built out of diversified storage structures. This proposes
> adding new tests to cover the following scenarios.
> # Tests space quota for storage policy = WARM
> # Tests if changing replication factor results in copying file as quota
> doesn't exceed
> # Tests if clear quota per heterogenous storage doesnt result in clearing
> quota for another storage
> The following cases have been covered.
> # Tests space quota for storage policy = ALL_SSD, covered by
> TestQuotaByStorageType#testQuotaByStorageTypeWithFileCreateAllSSD
> # Tests if overall space quota exceeds even if particular storage space quota
> is available, covered by
> TestQuotaByStorageType#testQuotaByStorageTypeAndTraditionalQuotaException3
> # Tests spaceQuota for storage policy = Cold, covered by
> TestQuotaByStorageType#testQuotaByStorageTypeWithTraditionalQuota
> # Tests if quota exceeds for DISK storage even if overall space quota is
> available, covered by
> TestQuotaByStorageType#testQuotaByStorageTypeAndTraditionalQuotaException2
> # Tests space quota with append operation, covered by
> TestQuotaByStorageType#testQuotaByStorageTypeWithFileCreateAppend
> # Sanity Test : Checks if copy command fails if quota is exceeded, covered by
> TestQuotaByStorageType#testQuotaByStorageTypeParent*Child*
> # Tests space quota with remove operation, covered by
> TestQuotaByStorageType#testQuotaByStorageTypeWithFileCreateDelete
> # Tests space quota with Snapshot operation, covered by
> TestQuotaByStorageType#testQuotaByStorageTypeWithSnapshot
> # Tests space quota with truncate operation, coveved by
> TestQuotaByStorageType#testQuotaByStorageTypeWithFileCreateTruncate
> # Tests space quota remains valid even with Namenode restart, covered by
> TestQuotaByStorageType#testQuotaByStorageTypePersistenceInEditLog and
> TestQuotaByStorageType#testQuotaByStorageTypePersistenceInFsImage
