An HBase snapshot is an immutable, point-in-time shallow copy of a table. It does not change over time. If you want to capture the changes made to a table since an old snapshot in a new snapshot, you must take a new snapshot.

Phoenix does not use the trivial serialization that you have written into your HBase table by hand. Use the Phoenix API to write the data into your table for complex data types. Or, create your view on your physical table using the TO_DATE function in your view definition to convert the VARCHAR data to a DATE.

HBase does not have to read an entire HFile into memory to service reads.

You need to add the directory containing hbase-site.xml that you want, not the file itself. This is how Java works. You specify jar files, an asterisk wildcard, or a directory.

You didn't need to remove the other valid classpath entry that you had previously...

You have specified an invalid classpath. You should be using: /usr/hdp/2.6.4.0-91/hbase/lib/* You can read https://docs.oracle.com/javase/8/docs/technotes/tools/windows/classpath.html#A1100762 for a refresher.

I've never heard of any issue where a truncate does not remove all data from the table (the regions are physically destroyed, so there is no way that the data could persist). Perhaps you have some process which is writing new data into this table in the background which you forgot about?

The commands you shared in your initial question are not what that post says to do for a Phoenix table mapped to an HBase table. You said you ran `CREATE TABLE`, but that FAQ instructs you to use `CREATE VIEW`.
