1. Selection of HBase and Hadoop versions
1. jdk version selection
An x on the icon means it is not supported, an exclamation mark on the icon means it has not been tested, and a green checkmark means it is supported.
It can be seen from the figure that the version after hbase1.2 supports JDK7 and JDK8, while the version between hbase2.0-2.2 only supports JDK8, and the version after hbase2.3 only supports JDK1.8, and JDK11 has not yet implemented Test, so here we choose the JDK8 version.
2. Hbase and Hadoop version compatibility
2. Hbase installation environment
The installation of Hbase needs to rely on the Hadoop environment (mainly the HDFS distributed file system), which is similar to spark, so the hadoop cluster needs to be installed first.
It is generally recommended to deploy HDFS and Hbase cluster services together, while nodemanager service is not recommended to be placed together with Hbase's RegionServer service, because the two services may compete for resources.
