question Spark : java.lang.IllegalAccessError: tried to access method com.google.common.base.Stopwatch.<init>()V from class org.apache.hadoop.mapreduce.lib.input.FileInputFormat in Support Questions https://community.cloudera.com/t5/Support-Questions/Spark-java-lang-IllegalAccessError-tried-to-access-method/m-p/293339#M216641 Hi Team,   I'm upgrading spark 2.1.1 to 2.2.1 and we had hadoop of 2.2.0. After changing spark 2.1.1 , I had to change hadoop version 2.7.2. Then it started throwing the following execption.   java.lang.IllegalAccessError: tried to access method com.google.common.base.Stopwatch.<init>()V from class org.apache.hadoop.mapreduce.lib.input.FileInputFormat   In our pom.xml we already have a version of guava.   <PRE>27.0.1-jre</PRE>  So I have added guava to exclusion list with no luck. I still get the same issue while running Junit (com.intellij.rt.junit.JUnitStarter.main)   <PRE><dependency> <groupId>org.apache.hadoop</groupId> <artifactId>hadoop-common</artifactId> <version>${hadoop.version}</version> <exclusions> <exclusion> <groupId>com.google.guava</groupId> <artifactId>guava</artifactId> </exclusion></PRE>      Any help would be very much appreciated Mon, 06 Apr 2020 09:33:47 GMT rs1992 2020-04-06T09:33:47Z
