, or another secure mechanism for copying the configuration files to your nodes.For most configurations, a restart is needed for servers to pick up changes.These include primary and backup Master instances, multiple Zoo Keeper nodes, and multiple Region Server nodes.This quickstart assumes that each node is a virtual machine and that they are all on the same network.Pseudo-distributed mode means that HBase still runs completely on a single host, but each HBase daemon (HMaster, HRegion Server, and Zoo Keeper) runs as a separate process: in standalone mode all daemons ran in one jvm process/instance.By default, unless you configure the This procedure assumes that you have configured Hadoop and HDFS on your local system and/or a remote system, and that they are running and available. The guide on Setting up a Single Node Cluster in the Hadoop documentation is a good starting point.Please read this chapter carefully, especially the Basic Prerequisites to ensure that your HBase testing and deployment goes smoothly, and prevent data loss.
First off, distributed systems are hard; making a distributed system hum requires a disparate skillset that spans systems (hardware and software) and networking.
Instead, send your report to the mailing list [email protected], which allows anyone to send messages, but restricts who can read them.
Someone on that list will contact you to follow up on your report.
If you think this designation should be reconsidered for a given feature or use pattern, file a JIRA or start a discussion on one of the mailing lists.
In the context of Apache HBase, /not tested/ means that a feature or use pattern may or may not work in a given way, and may or may not corrupt your data or cause operational issues. If you can provide proof that a feature designated as /not tested/ does work in a given way, please submit the tests and/or the metrics so that other users can gain certainty about such features or use patterns.
