Ahmed Hussein updated HADOOP-17100:
-----------------------------------
Description:
Replacing Usage of {{guava.Supplier<>}} are in Unit tests
{{GenereicTestUtils.waitFor()}} in Hadoop project.
* To make things more convenient for reviewers, I decided:
** Not to replace Object instantiation by lambda expressions because this will
increase the patch size significantly and require code adjustments to pass the
checkstyle scripts.
** Not to refactor the imports because this will make reading the patch more
difficult.
* Merge should be done to the following branches: trunk, branch-3.3,
branch-3.2, branch-3.1
The task is straightforward because {{java.util.Supplier}} has the same API as
{{guava.Supplier<>}} and the vast majority of usage comes from Test-units.
Therefore, we need only to do the following a "one-line" change in all 147
files.
{code:bash}
-import com.google.common.base.Supplier;
+import java.util.function.Supplier;
{code}
The code change needs to be applied to the following list of files:
{code:java}

> Replace Guava Supplier with Java8+ Supplier in Hadoop
> -----------------------------------------------------
>
> Key: HADOOP-17100
> URL: https://issues.apache.org/jira/browse/HADOOP-17100
> Project: Hadoop Common
> Issue Type: Sub-task
> Reporter: Ahmed Hussein
> Assignee: Ahmed Hussein
> Priority: Major
> Attachments: HADOOP-17100.001.patch, HADOOP-17100.002.patch,
> HADOOP-17100.003.patch, HADOOP-17100.006.patch
>
>
> Replacing Usage of {{guava.Supplier<>}} are in Unit tests
> {{GenereicTestUtils.waitFor()}} in Hadoop project.
> * To make things more convenient for reviewers, I decided:
> ** Not to replace Object instantiation by lambda expressions because this
> will increase the patch size significantly and require code adjustments to
> pass the checkstyle scripts.
> ** Not to refactor the imports because this will make reading the patch more
> difficult.
> * Merge should be done to the following branches: trunk, branch-3.3,
> branch-3.2, branch-3.1
> The task is straightforward because {{java.util.Supplier}} has the same API
> as {{guava.Supplier<>}} and the vast majority of usage comes from Test-units.
> Therefore, we need only to do the following a "one-line" change in all 147
> files.
> {code:bash}
>
> -import com.google.common.base.Supplier;
> +import java.util.function.Supplier;
> {code}
> The code change needs to be applied to the following list of files:
> {code:java}
>
> Targets
> Occurrences of 'com.google.common.base.Supplier' in project with mask
