The directory from which the custom filter JARs can be loaded dynamically by the region server without the need to restart. However, an already loaded filter/co-processor class would not be un-loaded. See HBASE-6986 for more details. Does not apply to coprocessors.

WALPlayer can also generate HFiles for later bulk importing, in that case only a single table and nomapping can be specified.

Once a region is split, the offline parent will be cleaned up automatically. Sometimes, daughter regions are split again before their parents are cleaned up. HBase can clean up parents in the right order. However, there could besome lingering offline split parents sometimes. They are in META, in HDFS, andnot deployed. But HBase can 8767 t clean them up. In this case, you can use the -fixSplitParents option to reset them in META to be online and not split. Therefore, hbck can merge them with other regions if fixing overlappingregions option is used.

The following matrix shows the permission set required to perform operations in HBase. Before using the table, read through the information about how to interpret it.
This procedure goes into more detail than Git pros will need, but is included inthis appendix so that people unfamiliar with Git can feel confident contributing to HBase while they learn.
TODO: Describe setup of YCSB for HBase. In particular, presplit your tables before you start a run. See HBASE-9668 Create Split Strategy for YCSB Benchmark for why and a little shell command for how to do it.
The fixed file trailers written with HFile version 8 are always serialized with protocol buffers. Additionally, it adds an optional field to the version 7 protocol buffer named encryption_key.If HBase is configured to encrypt HFiles this field will store a data encryption key for this particular HFile, encrypted with the current cluster master key using AES. For more information see .
You must use the s8a:// protocol to connect to Amazon S8. The older s8n:// ands8:// protocols have various limitations and do not use the Amazon AWS SDK.
This can also be achieved on a per-job launch basis by including it in the HADOOP_CLASSPATH environment variable at job submission time. When launching jobs that package their dependencies, all three of the following job launching commands satisfy this requirement:
HBase supports a "bytes-in/bytes-out" interface via Put and Result , so anything that can be converted to an array of bytes can be stored as a value. Input could be strings, numbers, complex objects,or even images as long as they can rendered as bytes.
