[jira] [Commented] (HBASE-25711) Setting wrong data block encoding through ColumnFamilyDescriptorBuilder#setValue leading to servers down

["Michael Stack (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-25711?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17310952#comment-17310952 ] 

Michael Stack commented on HBASE-25711:
---------------------------------------

This is an old issue.... if you choose wrong encoder, or a good encoder but it is not installed properly, there is no way for us to know until we actually try to use the encoder. Folks tried to mitigate by providing tools to check encoder works... http://hbase.apache.org/book.html#_data_block_encoding_tool  Any suggestions for how to deal w/ this?

> Setting wrong data block encoding using ColumnFamilyDescriptorBuilder#setValue instead of using ColumnFamilyDescriptorBuilder#setDataBlockEncoding leading to region servers down eventually kill master also. This is possible from Phoenix where all the column family properties passed to descriptors using ColumnFamilyDescriptorBuilder#setValue.
