Getting error while installing hail on cluster

I have set my `JAVA_HOME` as

> export JAVA\_HOME=/usr/lib/jvm/java-8-openjdk-amd64/jre/

Installation steps:

```python
apt-get update -y
apt-get install \
    openjdk-8-jdk-headless \
    g++ \
    python3 python3-pip \
    libopenblas-dev liblapack-dev \
    liblz4-dev -y

git clone https://github.com/hail-is/hail.git
cd hail && git checkout 0.2.72 && cd hail
make install-on-cluster HAIL_COMPILE_NATIVES=1 SCALA_VERSION=2.12.13 SPARK_VERSION=3.2.0

```

Error trace:

```python
2022-02-22 01:17:47 make[1]: Leaving directory '/home/dnanexus/hail/hail/src/main/c'
2022-02-22 01:17:47 make[1]: *** No rule to make target 'jni.h', needed by 'build/NativeBoot.o'. Stop.

Hi Abhishek,

Pretty sure your problem is that you have `JAVA_HOME` set incorrectly. It needs to point to the “jdk” (Java Development Kit), not the “jre” (Java Runtime Environment).

Yes, I found that my JAVA\_HOME was not correctly set because I only installed jre.  
So, I added the steps mentioned in hail documentation

```auto
apt-get update -y
apt-get install \
    openjdk-8-jdk-headless \
    g++ \
    python3 python3-pip \
    libopenblas-dev liblapack-dev \
    liblz4-dev \
    rsync -y

export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64

HAIL_VERSION=0.2.78

# Build Hail
# Following https://hail.is/docs/0.2/install/other-cluster.html
mkdir -p /builds
cd /builds
git clone https://github.com/hail-is/hail.git
cd hail/hail
git checkout $HAIL_VERSION

make install-on-cluster HAIL_COMPILE_NATIVES=1 SCALA_VERSION=2.11.12 SPARK_VERSION=2.4.4 HAIL_PYTHON3=python3

```

Earlier my `JAVA_HOME` was set to  
`export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/jre`

I had to reset it to `export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64`.

Hi all,

I got snagged by this too. NB that the 0.2 dev installation instructions ([Hail | For Software Developers](https://hail.is/docs/0.2/getting_started_developing.html)) refer you to the installation requirements for the end-user installation ([Hail | Install Hail on GNU/Linux](https://hail.is/docs/0.2/install/linux.html)), which have you install openjdk-8-jre-headless, but apparently not the JDK per se. In that case, it seems that the path /usr/lib/jvm/java-8-openjdk-amd64 is present but exporting it as JAVA\_HOME doesn’t suffice to install.

In any case, I was able to resolve it with:

sudo apt-get install openjdk-11-jdk  
export JAVA\_HOME=/usr/lib/jvm/java-11-openjdk-amd64

The docs might benefit from including language to that effect.

Thanks!

Thanks for the report! The next release of the docs will [clarify the need for the JDK](https://github.com/hail-is/hail/pull/12968).
