I am studying the content of the hbase-book repository. While doing so, I encountered the following error when running the Java file at https://github.com/larsgeorge/hbase-book/blob/master/ch04/src/main/java/coprocessor/LoadWithTableDescriptorExample.java.

We were configuring for hbase multiple nics and set both hbase.regionserver.ipc.address and hbase.master.ipc.address to 0.0.0.0. This caused hostname lookup issues which was a known issue years ago (we now know).

If my table has just 1 column family with 3 columns: A,B,C. And I read just 1 column, will the entire row be read into memory?
