Need to get to the bottom of this, before doing any performance testing.  If 
you don't have an search index on a node, you will not get reliable search 
results.

I would check to make sure Solr is running properly on the nodes on which you 
are not finding the index.  If you look at the logic for creating a local index 
[1], you should see some checks to see if the index is in metadata or on disk.  
You should see some entries in the logs that will show either success or errors 
on creation.  Check the error logs, to ensure you are not getting errors 
communicating with Solr.

Also, note that 2.1.1 is fairly old.  Significant improvement with batching and 
asynchronous writes to Solr were added in Riak 2.2, and the latest release of 
the 2.2 branch is 2.2.2.

Re: Unable to compile Riak on Raspberry Pi 3

[Alex Moore]

Hi cocos,

I recently did some testing around this and journaled the steps needed to
build KV and TS on Raspbian:

https://gist.github.com/alexmoore/7bbdece19223cea1e144e4d23a5ed7ec

This includes building Basho's flavor of Erlang, and the fix that Matthew
mentioned.

Thanks,
Alex

Re: Unable to compile Riak on Raspberry Pi 3

[Matthew Von-Maszewski]

A fix for that problem in leveldb/util/perf_count.cc already exists on the 
"develop" branch of the github repository basho/leveldb.  Download it and 
rebuild.

Unable to compile Riak on Raspberry Pi 3

[cocos]

Hello,

currenty I'm trying  to install Riak**on the Raspberry Pi 3 for testing 
purposes. I used the following instruction from basho:


http://docs.basho.com/riak/kv/2.2.2/setup/installing/source/

I'm having problems compiling it from source. I tried to compile it on 
Raspbian Jessie and then switched to Ubuntu Server 16.04. Both times 
with the same result. It is not compiling and aborts at a certain point. 
I don't know what causes the problem since it only says: `recipe for 
target 'util/perf_count.o' failed`. Searching Google and the mailing 
list from basho weren't successful.


The version of `gcc` is `gcc (Raspbian 4.9.2-10) 4.9.2`. The version of 
`Erlang` is  `Erlang R16B02_basho8 (erts-5.10.3)`


The commands i used are the following:

*Installing Erlang:*

wget 
http://s3.amazonaws.com/downloads.basho.com/erlang/otp_src_R16B02basho10.tar.gz


tar zxvf otp_src_R16B02-basho10.tar.gz

cd OTP_R16B02_basho10
./otp_build autoconf
./configure && make && sudo make install

*Installing Riak:*

wget 
http://s3.amazonaws.com/downloads.basho.com/riak/2.2/2.2.1/riak-2.2.1.tar.gz


tar zxvf riak-2.2.1.tar.gz

cd riak-2.2.1
make locked-deps
make rel

Any suggestions are welcome.

Hello,
currenty I'm trying  to install Riak on the Raspberry Pi 3 for testing 
purposes. I used the following instruction from basho:

http://docs.basho.com/riak/kv/2.2.2/setup/installing/source/

I'm having problems compiling it from source. I tried to compile it on Raspbian 
Jessie and then switched to Ubuntu Server 16.04. Both times with the same 
result. It is not compiling and aborts at a certain point. I don't know what 
causes the problem since it only says: `recipe for target 'util/perf_count.o' 
failed`. Searching Google and the mailing list from basho weren't successful. 

The version of `gcc` is `gcc (Raspbian 4.9.2-10) 4.9.2`. The version of 
`Erlang` is  `Erlang R16B02_basho8 (erts-5.10.3)`

The commands i used are the following:

Installing Erlang:

    wget 
http://s3.amazonaws.com/downloads.basho.com/erlang/otp_src_R16B02basho10.tar.gz

    tar zxvf otp_src_R16B02-basho10.tar.gz

    cd OTP_R16B02_basho10
    ./otp_build autoconf
    ./configure && make && sudo make install

Installing Riak:

    wget 
http://s3.amazonaws.com/downloads.basho.com/riak/2.2/2.2.1/riak-2.2.1.tar.gz

    tar zxvf riak-2.2.1.tar.gz

    cd riak-2.2.1
    make locked-deps
    make rel

Any suggestions are welcome.
