Today is a day we will never forget - infinimesh (https://www.infinimesh.io/) is starting and lifting off! Our Kubernetes, Apache Kafka ® and graph based Industrial IoT platform is entering the alpha stage! We have been working like maniacs over the past 14 months to bring a fully flexible, independent, patent and vendor lock-in free IoT platform to you! Soon it’s your chance to test and try it out, our closed alpha will be open for public on March 30, 2019 - Mark this date in your calendar!
An incredible platform comes to life
We believe smart and connected devices bring our society forward. Smart technology uses resources only when they are really necessary and thus prevents waste. On the other hand, when really required, smart things act and hence prevent accidents or simply enable a great user experience. We have started infinimesh 100% Open Source, without patents or closed software. Any software components we have developed, and to this we commit going forward, will be open - fo…
Three weeks ago I played with libhdfs and NFS, but I did not get the results I expected. Then my next idea was, why not to use Samba? Samba3x is stable and most OS can mount an exported share.
The main task was to research the performance and setup of this scenario, because samba has a lot of tuning mechanisms inside. Let's go!
I used a RHEL 5.7 and the delivered RPMs: #> rpm -qa|grep samba samba-3.0.33-3.29.el5_7.4.x86_64 samba-common-3.0.33-3.29.el5_7.4.x86_64
Like I described in "NFS exported HDFS" I mounted hdfs over fuse into the directory /123 via /etc/fstab:
Squirrel work with kerberos, however, if you don't want kerberos then you don't need the JAVA_OPTS changes at the end. My colleague, Chris Conner, has created a maven project that pulls down all of the dependencies for a JDBC program: https://github.com/cmconner156/hiveserver2-jdbc-kerberos
Note for kerberos environment, you need to kinitbeforeusing Squirrel. The above program handles kinit for you. If you are not using Kerberos and you want to use the above program, then comment out the following lines:
Then make sure to change the jdbc URI to not have the principal. Also, it's worth mentioning that if you use kerberos, I did have some issues with differing java versions. So try matching your client's…
