[jira] [Commented] (HBASE-30162) Parallelise .tableinfo file reads in FSTableDescriptors.getAll() during finishActiveMasterInitialization

    [ https://issues.apache.org/jira/browse/HBASE-30162?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=18082710#comment-18082710 ] 

Prathyusha commented on HBASE-30162:
------------------------------------

_This appears to be a duplicate of HBASE-27091 ("Speed up the loading of table descriptor from filesystem"), which already added parallel_ _.tableinfo_ _loading to  FSTableDescriptors.getAll(), will close this one_

> Sometimes when the underlying FileSystem is facing any partial AZ outages or the DN layer is too slow, the sequential read of tableinfo files slows down the Master initialisation, the plan is to use a threadpool to read tableinfo files of different tables in parallel.
