/bulkload - Used by Trafodion bulk load command - Load into tablename command and also used as the temp. directory to create links to the actual hfiles for snapshot scanning.

Bulk load bypasses the write-ahead log to enable faster loading of data by landing data into HDFS files, which are then read into HBase tables directly. Refer to https://hbase.apache.org/book.html#arch.bulk.load for more information. · */bulkload: *I got nothing. · */lobs: *Obviously, related to large-object processing but how? Also, these directory names are hard-coded in the installer. Are they hardcoded elsewhere or could they; for example, be prefixed with “trafodion-“ in a future release? · /trafodion-hbase-staging · /trafodion-bulkload · /trafodion-lobs OOverall, I'd recommend that directories and other objects use a prefix to reduce the likelihood of colliding with existing names. -- Thanks, Gunnar *If you think you can you can, if you think you can't you're right.*
