- Add Exception communication from server to client Iteration 2: Disk Quota - Random function that generates QuotaException. For testing end to end exception flow. Later this will be replaced by appropriate quota checks Iteration 3: Disk Quota - compute the bytes written to index and data files in each reducer. Add this information to the filename - estimate the total disk size in bytes needed for a <node, store> pair. Done by iterating through all the index and data files and getting theie sizes from the file names, after the job is run. Iteration 4: Disk Quota - In HDFSFetcher, fetch estimated disk size from metadata file - In HDFSFetcher, fetch disk quota limit for <node, store> pair using admin client Minor fix: Add log message Minor fix: Fix exception handling minor fix: Handle Quota Exceptions appropriately minor fix: Fix more exceptions More fixes for Exception logs More exception handling fixes Handling Quota Exception in AdminStoreSwapper Iteration 5: Fix disk estimation logic - Instead of renaing the .data and .index files, add the file size info to corresponding '.checksum' files - Introduce new CheckSumMetadata file that holds the following fields - checksum, data file size, index file size - CheckSumMetadata is similar to ReadOnlyStorageMetadata file in terms of serialization and deserialization minor fix: exclude unnecessary "_" in file names Cleanup debug logs Add quota checks - Determine if quota needs to be checked for the incoming push. For pre existing stores quota is not checked. They will be quota-ed in future. - Check if there is sufficient quota left for a new push. - Filter out stores that push data mistakenly to the Voldemort cluster. This is based on the assumption that for invalid stores, during build phase, a store definition is with 0 quota. All other stores that are onboarded through Nuage will have proper quota set already. More fixes: - Fix Non Quota Exception Handling. Propogates actual error message to client side. - Change getQuota() to getQuotaForNode() in HDFSFetcher. - Add debug log messages - Set zero Quota for stores that are created during Build and Push. We want all new stores to be pre created with appropriate quota via Nuage or via admin client.
