I am a beginner for BIG DATA(spark), Nowadays, I have installed spark2.4, So I want to know which best version should be chosen. Because I want to avoid conflict, which so bad.
Apache hadoop 2.7.7 is a stable release to be used. However, I've setup Apache hadoop 3.1.1 and running Spark 2.4 with it and have not seen any issues.
If you are doing it for practice better use 3.1.1 version and for production I would recommend using a more stable release.
Thanks,
Naveen

I need to download a TXT file from a SFTP server, I used ssh2-sftp-client and it worked perfectly but our production server runs on node 8.10 and the dependency requires 10 or higher.
Upgrading the node on the production server at this time is not an option, so I need an alternative to download the TXT file from the SFTP server that will work on node 8.10.
Thank you very much in advance.
I solved it using the version 2.5.2 of ssh2-sftp-client.

I'm not familiar with Linux and I need to install Apache Cassandra 3.1 on CentOS 7. I found a guide for Debian. Is there any guide for CentOS?

I could install it by following the steps in https://www.tutorialspoint.com/cassandra/cassandra_installation.html.

Could somebody please suggest me a good GUI client tool for Cassandra on Windows? I need something like Robo 3T (formerly Robomongo) for MongoDB.
DataStax (the maintainer of Apache Cassandra) has a tool called DevCenter . I use it, it gets the job done. A bit newer tool is DataStax Studio, which is more of a graph visualization tool, but I haven't used it, also check the pricing.
OpsCenter is a monitoring tool. It works with Apace Cassandra (the free one), with disabled features (all features availale in DataStax Enterprise).

I am looking for GUI based client for Cassandra database. Two project seems to be workable i.e. helenos, cassandra-cluster-admin. Unfortunately both of these projects seems no more being maintained. I have searched a lot over web but could not find any. Can you please suggest a free tool you know about?
I am using Datastax DevCenter and works so far with basic functionality to write queries, view list of keyspaces and tables.

You can use dbeaver (works with many databases):
