Thanks to Cloudera Blog HBase Customers upgrading to CDH 6 from CDH 5, will also get an HBase upgrade moving from HBase1 to HBase2. Performance is an important aspect customers consider.   We measured performance of CDH 5 HBase1 vs CDH 6 HBase2 using YCSB workloads to understand the performance implications of the upgrade on customers doing in-place upgrades (no changes to hardware).  About YCSB For our testing we used the  Yahoo! Cloud Serving Benchmark  (YCSB). YCSB is an open-source specification and program suite for evaluating retrieval and maintenance capabilities of computer programs. It is often used to compare relative performance of  NoSQL  database management systems. The original benchmark was developed by workers in the research division of  Yahoo!  who released it in 2010.  More info on YCSB at  https://github.com/brianfrankcooper/YCSB In our test environment YCSB @1TB data scale was used, and run workloads in...

How-to: Use Parquet with Impala, Hive, Pig, and MapReduce

-
Source: Cloudera Blog The CDH software stack lets you use your tool of choice with the Parquet file format – – offering the benefits of columnar storage at each phase of data processing.  An open source project co-founded by Twitter and Cloudera,  Parquet  was designed from the ground up as a state-of-the-art, general-purpose, columnar file format for the Apache Hadoop ecosystem. In particular, Parquet has several features that make it highly suited to use with  Cloudera Impala  for data warehouse-style operations: Columnar storage layout:  A query can examine and perform calculations on all values for a column while reading only a small fraction of the data from a data file or table. Flexible compression options:  The data can be compressed with any of several codecs. Different data files can be compressed differently. The compression is transparent to applications that read the data files. Innovative encoding schemes:  Sequences of ide...
