Hi All, I am running the hdf sandbox and trying to do a sample - couple of challenges 1. how to see the logs - when I ssh into the docker container by ssh root@172.17.0.1 - I don't see any /usr/hdf or /var/log/registry directories 2. while adding a avro schema - gets error ' Given schema is invalid' - attached screenshot Thanks, Avijeet ...

Hi All, I am looking at the HDF3.0 sandbox - couple of observations 1. It included HDFS, YARN, MR2, HBASE etc. - I thought these are not part of HDF so can HDF be all services except HIVE, Spark 2. In Ambari I see a lot of services with the briefcase with a + symbol - what exactly this symbol means - I started a few services still it shows the same symbol instead of green tick Thanks, Avijeet ...

Hi All, I tried HIVE insert/update/delete operations, I see that it launches a tez job and bit slow. I have a couple of questions - 1. when we use hive streaming processors (in nifi, streamsets) does it insert record by record? I believe no. just to confirm. 2. it seems bit risky to design an acid hive table, is there an approach where it can be used (such as IOT ) safely without having locking/concurrency issues etc. Thanks, Avijeet ...
