Hi, I cluster 2 nodes with each node 16GB Ram and 2-CPU Cores and yarn memory has been configured 8GB as recommended. I have set those configuration in tez as below mentioned link; https://community.hortonworks.com/articles/22419/hive-on-tez-performance-tuning-determining-reducer.html I don't know how to configure as my hardware configuration. I'm over process data around 6million record. It takes much time. Please tell me how do i configure to execute as faster/increase performance. Thanks in advance! Regards, Varun

Hi, I'm using HDP 2.5 with Nifi 0.6 version. I have 10GB CSV file, i want replace double quotes with pipe delimiter. Is it possible on NIFI Replace Text processor? or I need to write any external script like Groovy,Luna.

Thanks for the response. Already I have configured those configuration in hdfs. But still this issue can't able to resolve. while i'm trying to curl webhdfs by below command, it shows some error msg; [root@sandbox java]#curl https://sandbox.hortonworks.com:50470/v1/webhdfs/v1/?op=LISTSTATUS" curl: (60) Peer certificate cannot be authenticated with known CA certificates
More details here: https://sandbox.hortonworks.com:50470/ca/cacert.pem
curl performs SSL certificate verification by default, using a "bundle"
of Certificate Authority (CA) public keys (CA certs). If the default
bundle file isn't adequate, you can specify an alternate file
using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
the bundle, the certificate verification probably failed due to a
problem with the certificate (it might be expired, or the name might
not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
the -k (or --insecure) option. pls tell me how to resolve this issue.
