Briefly, this error occurs when Elasticsearch cannot access a specified path on the master node. This could be due to incorrect file permissions, a non-existent directory, or network issues. To resolve this, you can check and correct the file permissions, ensure the directory exists, or troubleshoot network connectivity. Also, verify the Elasticsearch configuration to ensure the correct path is specified.

This guide will help you check for common problems that cause the log ” path ” + basePath() + ” is not accessible on master node ” to appear. To understand the issues related to this log, read the explanation below about the following Elasticsearch concepts: blobstore, master, node, repositories.

Log Context

Log “path ” + basePath() + ” is not accessible on master node” class name is BlobStoreRepository.java. We extracted the following from Elasticsearch source code for those seeking an in-depth context :

 BlobContainer testContainer = blobStore().blobContainer(basePath().add(testBlobPrefix(seed)));
 testContainer.writeBlobAtomic("master.dat"; new BytesArray(testBytes); true);
 return seed;
 }
 } catch (Exception exp) {
 throw new RepositoryVerificationException(metadata.name(); "path " + basePath() + " is not accessible on master node"; exp);
 }
 }  @Override
 public void endVerification(String seed) {
