Errors installing Ambry on a Windows based machine

[salamehsameera]

Hi everyone,

I'm new here and I'm trying to install Ambry on my machine. These are the steps that I executed:
$ git clone https://github.com/linkedin/ambry.git
$ cd ambry
$ ./gradlew allJar
$ cd target
$ mkdir logs

Then, when I try to execute the following:
$ nohup java -Dlog4j.configuration=file:../config/log4j.properties -jar ambry.jar --serverPropsFilePath ../config/server.properties --hardwareLayoutFilePath ../config/HardwareLayout.json --partitionLayoutFilePath ../config/PartitionLayout.json > logs/server.log &
I get the following error:

$ cat logs/server.log

I see that it says that mount path has to be an absolute path, so I adjusted my command to be:
$ nohup java -Dlog4j.configuration=file:/d/users/sameeras/ambry2/config/log4j.properties -jar ambry.jar --serverPropsFilePath /d/users/sameeras/ambry2/config/server.properties --hardwareLayoutFilePath /d/users/sameeras/ambry2/config/HardwareLayout.json --partitionLayoutFilePath /d/users/sameeras/ambry2/config/PartitionLayout.json > logs/server.log &

And the result is:

$ cat logs/server.log
log4j:ERROR Could not read configuration file from URL [file:/d/users/sameeras/ambry2/config/log4j.properties].

Does anyone have any idea what could I be missing? Thanks in advance!

Hi @salamehsameera,

I will try this out on my windows machine later today, but could you try changing the paths to start with D:/ instead of /d/ (assuming D is the drive name)? Also, you may want to try removing the drive specifier (e.g. /users/sameeras/ambry2/config/log4j.properties instead)

Thanks @cgtz, I tried both and it did not work out unfortunately, here's the log output:
