Ask ten DBAs for a definition of ‘Big Data’ and you well get more than ten replies. And the majority of those replies will lead you to Hadoop. Hadoop has been the most prominent of the big data frameworks in the open source world. Over 80% of the Hadoop instances in the world are feed their data from MySQL1. But Hadoop is made up of many parts, some confusing and many that do not play nicely with each other. It is analogous to being given a pile of automotive parts from different models and tyring to come up with a car at the end of the day. So what if you do if you are wanting to copy some of your relational data into Hadoop and want to avoid the equivilent of scraped knuckles? The answer is Bigtop and what follows is a way to get a one node does all system running so you can experiement with Hadoop, Map/Reduce, Hive, and all the other parts.

Bigtop is an Apache Project self …

Time flies and MySQL Connect is just around the corner...Schedule Builder was launched last week to help you build your own schedule, selecting and pre-enrolling in sessions you plan to attend.

You can check out the program in our content catalog as well as via a new Focus on MySQL Connect document listing all sessions with time and location. If you’d like to expand your InnoDB knowledge, below are the sessions specifically focused on InnoDB …

We’ve all been through downtime at some point and deplore the lost work and productivity that comes with it. And the only thing worse than server downtime is having to report that downtime to frustrated customers who are depending on your service for their business.

Yesterday, AWS server issues meant downtime for highly trafficked sites Instagram, Vine, Airbnb, and IFTTTA. According to AWS’s health dashboard, the company’s North Virginia data center may be to blame.

The fact is, any cloud system is subject to outages, from Yahoo Mail to Microsoft BPOS and VMware; however, outages aren’t and shouldn’t be business as normal.

While we never wish for anyone to experience downtime, when stories like AWS hit the …

I am certainly not a knowledgeable Perl person, however I recently ran into the error Can’t locate MHA/MasterMonitor.pm on Red Hat 6.x. I have installed MySQL MHA on various systems before without any issues.

$ masterha_manager -version
Can't locate MHA/MasterMonitor.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /usr/bin/masterha_manager line 26.
BEGIN failed--compilation aborted at /usr/bin/masterha_manager line 26.

The issue was that MySQL MHA is not installed in any of the acceptable default paths for this disto default installation.

$ find / -type d -name MHA
/usr/lib/perl5/vendor_perl/MHA

The fix was simple on this OS, but I expect there is a correct Perl approach?

Thanks to everyone who attended last week’s webinar on MySQL security; hopefully you’ve all gone out and set SELinux to enforcing mode if you weren’t already running that way. If you weren’t able to attend, the recording and slides are available for viewing/download. But now, without further ado, here are the questions which we didn’t have time to cover during the presentation.

Q: Do you have a favorite software firewall you recommend that I can run on an EC2 instance in front of my MySQL server?
A: I’d probably just do this with iptables. Any of the other Linux-based software firewall packages are all going to be wrappers around iptables anyway. However, if …

Recently i had to manage big database installation that was running out of disk space. The partition on which the mysql datadir was located only had a few gigabytes free. Resizing the partition was not possible without a long downtime so that was no option. The installation had only innodb-tables so using symlinks was also not possible.

Luckily they were using MySQL 5.6 and the server had another partition with more than enough disk space available so i decided to use that partition for the biggest tables.

First get the 15 biggest tables:

root@mysqlserver [(none)]> set global innodb_stats_on_metadata=0; select table_schema, table_name "Table Name",round(sum(data_length+index_length)/1024/1024/1024,4) "Size (GB)" from information_schema.tables group by table_schema,table_name ORDER BY round(sum(data_length+index_length)) DESC LIMIT 15;
 Query OK, 0 rows affected (0.00 sec)
