Error message

This warning occurs when using Hbase:

Impact

The HBase operation will be slower.

Hi davidoonlaptop, The above error tells us Hadoop native libraries are not available in HBase context. You could probably confirm this by running below command. This command will show many false statements.

$ /usr/bin/hbase --config /etc/alternatives/hbase-conf/ org.apache.hadoop.util.NativeLibraryChecker

To solve the issue permanently gently export LD_LIBRARY_PATH environment variable in hbase-env.sh. meanwhile you can confirm this by providing LD_LIBRARY_PATH in previous command.

$ LD_LIBRARY_PATH=/usr/lib/hadoop/lib/native/ /usr/bin/hbase --config /etc/alternatives/hbase-conf/ org.apache.hadoop.util.NativeLibraryChecker
