Hi, all: About a year ago, we introduced 'multiple dirs for temp data' to solve disk hotspot problem in data loading.
This feature enables carbon randomly pick one of the local directories configured in yarn-local-dirs when it writes any temp files to disk (for example: sort temp files and fact data files). For about one years' usage in productive environment, this feature turns out to be effective and correct. So here I propose to enable the related parameters by default. The related parameters are 1. `carbon.use.local.dir` : Currently it is `false` by default, we will turn it to `true` by default; 2. `carbon.user.multiple.dir` : Currently it is `false` by default, we will turn it to `true` by default. -- Sent from: http://apache-carbondata-dev-mailing-list-archive.1130556.n5.nabble.com/
