Why Hbase only return 3 version for a cell no matter I set { VERSION = 100} or not

    v = data.getValues(XP_PHONE);
    for (int i = 0; i < v.length; i++) {
        put.add(COLFAM, COL_PHONE, i, Bytes.toBytes(v[i].trim()));
    }

This is the code I used, the phone numbers should be 8 or more, but after the put has been submitted, I only can view the latest 3 version result in hbase shell. Why? and how to fix it?

If you insert same value to a column 10 times and request a complete lit of all value retained you will only receive the last 3 versions by default. Which means you will only receive what is configured in the table schema.

you must use public Get setMaxVersions(int maxVersions) to get more versions or use setTimeStamp(long timestamp) to set the version you want to get

When a table is created the max number of versions that can be stored is set. The default for max versions is 3:

http://hbase.apache.org/book/schema.versions.html

You can alter an existing table to change the max number of versions.

Using hshell:

hbase> alter 'table_foo', {NAME => 'column_fam_foo', VERSIONS => 100}
