gianm opened a new pull request, #1270: URL: https://github.com/apache/parquet-mr/pull/1270
Addresses https://issues.apache.org/jira/browse/PARQUET-2429. Currently input buffers are grown one chunk at a time as the compressor or decompressor receives successive setInput calls. When decompressing a 64MB block using a 4KB chunk size, this leads to thousands of allocations and deallocations totaling GBs of memory. By growing the buffer 2x each time, we avoid this and instead use a modest number of allocations. -- This is an automated message from the Apache Git Service.
