I think that it should be done by means of a > new Plugin framework, because this seems to be a general capability/feature. > As a future enhancement this can become a part of a more general > StoreFileWriter/Reader plugin architecture. But I need only Meta section of a > store file. > This could be used, for example, to collect rowkeys distribution information > during hfile creation. This info can be used later to find the optimal region > split key or to create optimal set of sub-regions for M/R jobs or other jobs > which can operate on a sub-region level. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
